This topic has become civil enough that I think I can say stuff.
First, "ya". "and" is a good translation for that sentence, because Gohan and Gotenks (or rather the components there of) would both be revived, along with other people. It doesn't indicate who is coming to fight; the object is the same, but the object is nonspecific and refers to a group. Umm... something like "Your plan is/was to revive Gohan, Gotenks, Etc, for the purpose of fighting". The "ya" in this context would indicate that the revival could include Gohan and Gotenks, or Gohan, Gotenks and Piccolo, or Gohan, Gotenks and the Trix Rabbit; it doesn't indicate who of the group would fight, just that their revival makes them potential fighters. Actually I think that fell apart in my last sentence. I lose.

The fact that the fat Buu/Boo (I have no idea which to use here... :O ) was disconnected before the transformation into "buff" Boo seems to be the strongest argument I've seen for Chibi Boo's power. I find SS2Vegeto's counter argument possible, but unsubstantiated, so it seems impossible to prove either way on this point.
As for the size issue.
Is it anime only when Goku and Vegeta manage to create a hole from inside Shin Boo through which they can see daylight before it is closed?
This reminds me of a discussion somewhere on Daizex (off hand, I don't remember where it is). Consider that in order for a force to affect an area, it either must act on the whole area, or be transmitted through the area by other means. (My termenology might be slipping, which usually results in someone pointing it out, me making a long response, and then the thread getting sidetracked and I come out as the idiot... Umm... so... I hope my meaning is clear.). To illustrate what I'm talking about (and not prove a point on this topic, just to... ur... set up that part), think of shooting a bullet (or ki blast) through a large disk. If the disk is of a Buu-like stretchy substance, the blast might be able to go through, but the rest of the disk will be fairly in tact, even if it is stretched some, because it'll recoil. If it's shot through a rocky substance, the same thing might happen; not through elasticity, but just because only part of the rock is damaged. But say we have something made of a brittle substance. Same resistance as the other two, but the force of the blast is transmitted through the whole object and it collapses afterward.
And that pointless bit of example brings up...
The entire body has the same resistance (in theory; ki can be focused in various areas, things can be tensed... but over all), so... does a blast strong enough to over come the resistance have the same effect if it hits a small area, or a large one, given that it has the same power to penetrate the body? So basically, if tiny Goku and Vegeta blasted a hole in Shin Boo's head, it's a hole. If they're the same size and use the same blast, only it is bigger, would it just make a hole in his head?
Of course, we ask: wouldn't more energy be involved? How does the size affect their abilities to build the size of the blast? What about everyone that would have been caught in a huge blast formed by tiny Goku? So ... I think I confused myself rather than contributing anything... but for some reason I post anyway.
The ... somewhat dead point about Goku's (rough paraphrase) "So, we have to defeat you in here, then find a way out?" ... It's a retorical question, a reaction... this happens a lot, especially in fiction (like the ever irritating skipping-of-recap by having someone say, "So, you guys did all of the stuff you just told me?").
I'll try to make a good example for comparison, but if it is bad, well... I'm sorry.
Say we have a couple of random warriors, fighting a random enemy (barring all Bio Broli references, let's say it's a gelatenous creature). The enemy is pretty unphased by the warriors' attacks because of its jello-ness, but water does seem to cause damage (dissolving, maybe?) to the parts of it that it hits.
One of the warriors notices this (because... something wet hit Jello-man), and says to the other, "It looks like water can hurt him!" To which the other responds, "So now we have to find enough water to drench him without getting killed in the process?". Somewhat awkward, but understandable. I think that's sorta what's going on with Goku's sweatdrop statement/question... but... it really doesn't matter, I guess.
I like how this discussion has gone in the last two pages compared to the rest.
... no proofreading of this post. I hope I know what I'm doing.
