And how do you think WE all learned how to work on our bikes? ? ? ? Give the guy a chance.

Hellastoned, no one has mentioned it yet but you can find a lot of helpful details on doing all the tasks you'll need to do by going to http://www.parktool.com/repair/ . Hover your mouse over the area you need advice on and click when it turns into a finger.

Since it sounds like you're new to bicycle working there's also a wonderful resource on bicycle work and knowledge at www.sheldonbrown.com .

Between those two resources and some help from here you shouldn't run into anything you can't handle.

The only real issue is bolts threaded into aluminium parts. You obviously want to torque them down well enough to hold but not hard enough to strip out the threads. If you doubt your ability to do this then go buy a smaller inch-lb torque wrench in 1/4 inch drive size and pick up a set of 1/4 inch drive metric sockets and metric allen key tips from a tool store. With time you'll develop a feel for how tight to make stuff and won't need the torque wrench but for now it could save you a lot of time, frustration and replacement parts costs. A basic one from somewhere like Harbour Frieght for $15 isn't all that flashy but it'll keep you from doing damage. Or if you're confident that you have a feel for this sort of stuff then you can skip it.

Now having said all this if you're the sort that doesn't work with tools much and wouldn't know how to begin doing things like changing the oil on your own car and smiles with glee when you manage to put air in your tires without harm to yourself or the tire then I'd have to say take it in to the shop. But if you've tinkered successfully with other mechanical work then working on a bicycle is just an extension of that with a few new bits of skill and knowledge to be picked up along the way.
