Client Sided :
VeniceFX/Color Tweaker from Realmware (If the server allows it) + SMAA Injector(If punkbuster allow it or does it?) + BF3 FreeCamera Tool (Unranked servers)
Or if Server Sided Settings :
No Color Grading/blue tint + No Suppresion + No dubstep lens flares + Day-Night Cycle + Dynamic Weather Cycle(dunno if possible) + All vehicle weapons/extras unlocked + more if possible

tl;dr
Make Battlefield 3 like Battlefield 2!
So, What mods and/or settings will you use when hosting or playing venice?
