Hey Steve,
Welcome to the forums. Great place to find out info on our Audi's. Yes, you can do the brakes at home. If you have the proper tools it generally onlytakes about 90-120 minutes to do all four, if you've never done it before. All you need is a little mechanical know-how, a couple of sockets, maybe a couple of wrenches-for leverage on difficult bolts, and a brake-caliper-tool. You can find this gift from mechanics heaven at Harbor Freight, for about $30.00+ S&H at:

Or, if you're more adventurous,on eBay for about $25.00+ S&H at:

OR, if you're RILLY cheap (which I doubt, of you'd've bought a Corolla), if your local auto -parts store does tool-lending, you will only have to leave a returnable deposit, which is refunded in whole or in part, upon return of their tool-set.
Brakes are one of the easiest things you can DIY on a car, generally. Lemme know if you need a step-by-step...
