Thanks for all the replies! I actually did do a search before posting and read a bunch of threads, but it seemed like most people really needed to CLEAN their BBs and not just dry them out. I'm happy to report that about 24 hours after the incident, I've put the battery back in and everything seems to be working just fine! The 0/Space and OP/. keys aren't as responsive as they should be, but they still work. I'm hoping they'll get better with time. I just left the battery out and let it sit on the windowsill in the sun today with the seams propped up. I turned it a couple times, but god only knows if that made any difference whatsoever.
Anyway, thanks for all the replies, and I'm proud to announce that my 7130e is alive and well!!
