You're right, it's pretty basic, all you need to do is lift the back hatch and remove the 3 screws keeping the tail lights in place. They'll pop off with a little effort and then the bulbs and sockets are your standard rotate to pop in and out type. As far as which bulbs to use, 1157's seem to be the ones you want. Although I have 1156's (single conductor bulbs) in mine but I also have single conductor sockets, so I would look into the empty bulb sockets and see if you have a single or double conductor socket and replace accordingly.
