It's possibly worse than a dead battery; the computer should still work without it. Whatever sparked when you were trying to disconnect the battery could have damaged something on the logic board.
Disconnect the battery connector and see if it starts up when you connect the MagSafe connector - I've seen a few "dead" MacBook Pros (no power, no lights on MagSafe - SMC or PRAM resets don't help) that miraculously start up when the battery is temporarily disconnected. Once started, I shut them off, reconnect the battery, and they work fine (and the battery still has a reasonable charge).
Otherwise, you probably cooked something - with the broken USB port, you probably can use a new logic board anyway. I knew someone that fried their USB ports (both of them) and did the flat-rate repair from the Apple Store to get a new logic board out of warranty - if you look around the Internet, it seems to be a thing, but not advertised or offered in every situation:
I'd just make a Genius Bar appointment, explain what was going on, and just see what they can do for you. Since your machine is still being sold, you might have more luck.
