Sorry I`m not able to respond that often , but I`m really ill and I can barely stand up . Anyway , let`s get started :
Because, when he mentioned to Vegeta, "I know! You're gonna Gohan and Gotenks to fight with us!" he already faded from SSj3 and mentioned he was actually losing power after almost reaching his full power.
Ok, let me ask this, if SSj3 Gotenks and Ultimate Gohan weren't stronger than Goku, and Goku couldn't use SSj3 anymore, what would be the point of even wanting them to come in the first place?
He (Goku) mentions he wanted Gohan and Gotenks to come and fight. But never states it'll take all of their combined efforts to actually beat Chibi Boo.
Moments sooner prior to saying to Vegeta that he`s gonna bring Gohan and Gotenks to fight with them , it was stated that at full power , Goku can obliriate Kid Buu . Now if both Gohan & Gotenks were stronger than Goku at full power , there would be no need to mention bringing them both , since only one of them would be enough to obliriate Kid Buu , according to you . Thus , since he said
both it means that neither of them are stronger than Goku`s full power .
Why would be the point of bringing them ? I suspect Gohan is not much weaker than Kid Buu , more like a 1,1 difference , but still enough for Kid Buu to have a slight advantage in their fight . And with both him and Gotenks fighting against Kid Buu , they would have a chance at beating him. And since Goku says to bring them
both it
does mean that it takes their combined efforts .
It matters a lot. I think it's highly illogical that all the ki within him vanishes/drains out instantly (regardless of a long lasting transformation). When you pull the stopper out of a tub full of water, it doesn't instantly blast down the drain with extreme speed and force. The Ki drained out, some of it was weaker, some of it was stronger. Everthing drained out, and Buu's body changed in accordance to that.
Not in this case since the power actually
increased . You can`t increase power with something you don`t have .
If they had no desire to involve anyone else at that point (or need, from Vegeta's perspective at the time), it wouldn't have even mattered. At that point in time, Goku was the only one who could beat him...because, at that point in time, he was the only one stronger than Buu. There's no need to consider the power's of dead men theoretically, in such a statement regardless of the possibility of ressurection, when at that point in time they are dead. That statement does not have any need to involve them. It could just as easily, and probably was, as statement concerned with the hear and now.
Not needing somebody else and somebody else not being able to fight Kid Buu are 2 different things . If Vegeta truly would have meant only for that moment , then he would have said something like "Now that Gohan and Gotenks are dead , you are the only one who can fight him" but he
didn`t .
I made a slight error, here. If you want to get really literal on this point, the word translates directly to neither "or" nor "and". You, in turn, appear to have used a babelfish translation, or some other internet website/text translator, which is one of the single worst sources I could possibly think to rely on. If someone else translated it for you, they probably used one. If they say they didn't, they're probably lying, because I get the same results on babelfish. I've done my homework, and I've got a Japanese - English dictionary right next to me. I can translate again and break it down this time if you or anyone else can get me the Romaji so that I can just look it up in a few minutes. It's in Katakana right now, and I still need to cross refference a lot of different sources to get something clearly accurate on the non-romanized characters.
EDIT: I checked up on it. The term in question, "ya" can be used to mean and as well as or, depending on the character(s) used. In this instance, it is neither "and" nor is it "or". As has been said by Mystery Person X, the particle や (ya), not only doesn't mean "and", but isn't even as strong as definitely one or the other - what he's talking about is someone, with Gohan and Gotenks as two possible examples.
I asked 3 persons who speak the Japanese language , I`ve myself used 2 translators , and I`ve also checked 4 mangas .
1.The Viz Manga , the one that most people on the forums go about , which is the official manga says
Gohan and Gotenks .
2.The French Manga ,which is again
official says Gohan
and Gotenks:

3.The Spanish Manga also says Gohan
and Gotenks :

4.The Italian Manga also says Gohan
and Gotenks :

I`ve checked 2 different dictionaries (one is an online one , and the other is a program for translating)
The first one :

The second one :

So 3 official mangas (not so sure about the spanish one) , 3 japanese speakers and 2 japanese dictionaries
all say the same thing , yet you say different .

Besides , all the official mangas are translated by
professionals , and eventough sometimes they make mistakes ,
4 different mangas saying the same thing is a little too much .
If their power levels didn't weaken, there's no reason to assume that size made that much of a difference. Vegetto certainly didn't have much trouble as a coffee drop (in fact, it was even more difficult because Buu couldn't attack him), and Goku had blatantly stated that he was still stronger than either of them...so if their power levels didin't drop, and Shin Buu is still stronger than either of them, then Shin Buu>>>Goku>>>Chibi Buu. Further, Goku ends off by emphasizing to Vegeta not simply the point that they would fail to destroy him if they had gone out in an unfused state, but that they would both be killed. Goku had never insinuated that he could win either...he recognized the fact, and questioned Shin Buu on it, and to me he looked quite aggrevated. We've never been shown that Shin Buu has any extra advantages within his own body other than the ability to move freely through it, and such has never been hinted at. It doesn't seem rational to me to assume that he probably did regardless, simply for the sake of one scenario becoming more plausible in that instance. And if I had a power level marginally higher than my opponent's, I wouldn't be too worried about the safety of my own life, regardless of something like stature.
There`s a difference between a flea and a candy and there`s also a huge difference between Vegeto & Goku . And no , Goku
didn`t state that he was stronger than them , in the Japanese manga he says that he is too strong , not that he is stronger than them . (the literal translation is "His strength doesn`t serve us at all" . And if you`re about to fight somebody inside his own body , and even worse , a person who can regenerate (And buu could most likely regenerate inside his own body since all the enviorment was practically him) , then it`s only normal to panic like they did . But even in those conditions , Goku insinuated that they will beat him and find an exit (Why exactly would he question Shin Buu , when it was obvious ?) .
