This is an old post but shows up high in searches, so I figured it would be useful to include a link to this Basic Guitar Setup guide available on Gibson's site.

That guide is part of the Tech Tips section http://legacy.gibson.com/Support/Tech-Tips.aspx
Even when findable through Google, I got those resources from calling Gibson's Customer Service on the phone.
