This advice is very much based on your playstyle alone. This means very diffcult to obtain no-swap heal scroll UMD and useless (where it really matters) assasinate DCs. OTOH, you will perform better against constructs and undead.
It's your choice, but I wouldn't gimp UMD and especially assasinate DCs on a rogue -- you can have so much fun with it and be so effective in epics.
On a 36 pt helf/human I would go
Str 16
Dex 15
Con 15/16
Wis 8
Int 14/16
Cha 8/10
You will be a hell of a trash destroying machine and have very nice DPS against raid bosses, while maintaining full skill abilities.
