Can't help with the lcation of a pro-shop, but will tell you that most of what you want done can be done fairly easily by you. If you have a set of Allen wrenches there isn't much to figure out when it comes to mounting a rest and sight. In the long run it pays to learn some of this stuff.
In the inrterim you might try downloading a copy of Easton's Tuning and Maintenance Guide from www.eastonarchery.com. It explains most of what you need to know about setting things up on a bow and then shows several methods of tuning a bow/arrow combination. You will learn the proper termns to use, too, which comes in handy when asking questions on any forums you frequent, including this one.
As for registering? Try a phone call to Joel at Martin Archery. Phone number is 1-800-541-8902 for customer service. Hopefully he can set you up. And don't tell him I told you. I think he's about ready to kick me in the behind as it is.
