I don't know if it gets easier, but definitely less confusing once you just kinda learn to roll with it.
I don't know much about the actual Sylar, no. I really don't want to know, and it's not like Peter - or anyone else for that matter - is all that fond of talking about him. But considering we had two Peters at one point, and two Claires, and two Hiros... I'm gonna go with yes. He could easily be here while Gabriel is also here.
Which really is just another reason we have to be careful with Gabriel. The last thing we need is two Sylars running around.
