What books should I read before Star Wars the Old Republic MMO?

I like reading the corny video game books that are out before any rpg I really want to get into. I read all the warcraft books back before the WoW launch.  I've read all the Mass Effect and Dragon Age books, the Witcher books, some Starcraft books etc etc. 
I wanted to read some Star Wars books before the MMO is out but I have no idea where to even begin. There are tons of star wars books out there, so i thought I'd ask if any of you fine gentlemen could give me a list.
