As someone new to comic books in general, I wholeheartedly second the recommendation of coming to the Small Press Expo. Besides the absurdly large San Diego Comic Con (which just came and went), this is probably one of the best conventions as it's quite cozy and gives you lots of chances to talk with creators as well as find books that you aren't likely to find at your comicbook shop.
If you're able to come at the end of August and you want to hit a large gaming convention, DragonCon might be for you. Though i've never been to it, I've been told that it's one of the largest gaming conventions on the US East Coast.
