GAOSP 2.3.4, what is the best option for Apps

I have just upgraded from 1.5 android to 2.3.4 via GAOSP nightly, i have used the cynogenMod7 Google Apps along with it. Apart from the battery issue i posted in a seperate thread, i am noticing that sometimes the keyboard doesnt press right, plus when i am trying to press on an app, the screen slides or someother adjacent app gets pressed ? How to solve this problem ?

Also i think maybe there are some other better app package could also be installed, Is the light Google apps only for froyo build or can they be used for this nightly gingerbread 2.3.4 build as well ?

Thx
