Here's the....I guess it can be called challenge.
I'm joining one of the most experienced GM's d&d 3.5 campaign this weekend and I need a really heavy hitting rogue. So I'm trying to do everything I can to amp up that lovely class feature sneak attack but I have never played a rogue before so I'm kinda swamped. So if any of you can tell me what feats a 5th level evil (planning to be an assasin) character should take please help me out.
Oh and also if you have any recommendation for magical items that may be of interest to said character that would also help alot.
::Edit:: A friend of mine was telling me about improved sneak attack and it sounds nice but he didn't know the prereq so one if anyone knows please tell and also should i go for it
::Edited part 2:: I should probably mention that the rogue is using two daggers sorry bout the lack of info
