MacBook Air 13" keyboard imput incorrect, not charging?

Hello!

My Macbook air 13" mid 2011 model is having problems after I spilled some water on it. It boots fine, can access the intered and all that jazz, but some keyboard keys don't work, or do other things. Also, the air isn't charging, but when I plug the charger in it comes up not charging, and the light on the charger doesn't illuminate. Lastly, after about 20 seconds of use, left clicking becomes right clicking and it's impossible to left click, even with a mouse. This can be fixed by closing the screen and reopening it, but the effect doesn't last.

Thanks!
