I once had to setup an RG270 for a friend, and BOTH of the posts leaned towards the neck. I manage to achieve an ok, pretty stable tuning (well, as good as you can get it with that type of trem), but it was just luck because they were tight in the position. Seems to me the holes have been drilled that way.
Anyway, remove your trem and check if you can move the post back and forth. If its not tight, you could try to pull the anchor out and glue it to the wood in a 90 degrees angle.
And you're right, a better trem is useless as long as the anchors aren't set tight into the body.
But there could also be other reasons for the tuning instability of your trem. On my first Ibanez, the TRS was driving me nuts until I realised that the fine tuners were so loose that they screwed themselves further out just by changing string tension (-> doing pull-ups). Got a cheap Lo-Pro Edge and now everything is fine.
ps. Sorry for my lame english!
