Most certainly your keybord/topcase is dead. Liquid doesn't do them any good and can cause all sorts of weird behaviour. You will have to change it. Apple, in some cases, at least here in Germany, insists to replace the whole upper case. That's not neccesary, you can buy sole keyboards from 3rd party suppliers on eBay and the like. But as you're having trouble with the trackpad you might have to change the lot.
