Hey everybody, I'm not quite sure on where to go on accessories for my recently bought Rebel XSi.
So far I have the kit lens, a "nifty fifty" lens, nice camera bag, and a Sandisk Ultra II 4GB card.
Filter(s): I was aiming to get a cheap Quantaray UV filter and B+W CP filter, but all the different kinds of focal lengths on the B+W scared me. Should I be going for the 77mm F-Stop one?
Tripod: IN PROGRESS - Manfrotto 055xPROB w/ 488RC2
Lens: As for lens, I'm at a loss on where to go. The kit lens seems okay for my everyday needs so far, but sometimes I wish I had a bit more zoom to it. I may be dragged around to take pictures of people and events (indoors and outdoors), so I bet that will be a factor too of what lens I should go for. But I personally do not think I need more lenses when I obviously need accessories instead at this starting point.
External flash: SOLVED - Canon 430EX
My budget is around $800. I'm hoping to not spend all of it, so deals are always a good thing. 
Many thanks in advance! 
I have a 18-55mm and fixed 50mm...so I guess I should go for a 50mm filter?
