If he had trained even for just a few years out of those as a precaution, or even a few months, he would be much better prepared for anything that could threaten him. And during that time there was probably nothing more beneficial for his interests than doing that. But he just didn't..
To train for what?!
He destroyed planet Vegeta and with it the only realistic threat he could face in his life. The only two beings that could kill him, Majin Buu & Beerus weren't a threat for Freeza. It's been thousands of years since Buu last appeared and of course Freeza wouldn't have a motivation to train for a monster that probably won't appear in his lifespan.
As for Beerus, well he didn't say he can become stronger then him, he said he could became even stronger then Goku that defeated Buu.So maybe he DOES discover something about him in this movie that he didn't know, something that will push him even beyond Beerus's power.
Or maybe he just though that it's ridiculous to train for Beerus when he sleeps for 50 years, awakens to destroy a planet or two and then he goes back to slumber. So the chances that Freeza will be facing Beerus in his life span are just slightly higher then for facing Boo.
And as for not training after Namek..Well there are two logical explanations:
1. Freeza's 100% on Namek matched SSJ Goku, he lost because he started to lose his power. When he returned as Mecha Freeza, he was stronger then his 100%, which would mean that he was stronger then Goku on Namek, and he even brought his father with him. He was eager for revenge and he thought it would be more then enough to defeat Goku and destroy the planet.
2. Simple, he couldn't train with all of the robotic parts on him.
