If you're going to do regular work on your Wing, I would suggest you get a service manual. You can get them in printed form or on CD. They will give you the step by step on all the maintenance you'd ever do, and most you won't, but it's there if you need it.
Check out WingStuff; they have them. There are other places you can buy them from as well, I just remember that WS has them off the top of my head.
