The screws on the back are Torx bits size T6. You can pick up that type of screwdriver at Sears (I got a set of 12 micro screwdrivers marketed toward jewelers and hobbyists from there - lifetime guarantee) or maybe a local hardware store. Unfortunately, I'm not sure that once you're inside you can do a lot to revive your calculator. Some liquids can really take their toll on electronic circuitry, and you will probably need a volt meter and some more sophisticated tools to test whether your components are still good. Your best bet is probably to contact TI and see if they will repair it for cheap. Otherwise, I've seen (and bought) some TI-89s for $50 or $60 off eBay and Craigslist.
