I have the trait that makes me shoot 20% slower and 20% more accurately. This svcks when I'm trying to shoot my pistol and I want it gone. Is there a mod that lets me re-trait or remove a trait or anything similar?

Typically, if you wanted to remove a perk, you'd find the FormID and type 'player.removeperk xxx' but I don't know if it's the same with traits. You could try opening the GECK and seeing if it's in there. Sorry if this wasn't helpful, all I know how to do is remove perks.

This works for me. You rebuild your character one level at a time up to your current level.

FYI, traits pretty much are perks - just with a "is trait?" flag set on it -- so I'd imagine what works for perks, should work for traits...

Going from memory, you still use the perk command.
