Astronomoics is a online catalog I buy a lot of stuff from. One of the reasons I go to them is that they are pretty close to me (about a 2 hour drive - in Texas, that's close) if I want to go to their store and see the stuff in person. They have a pretty good page on how to pick a telescope on their website.
Click on "How to pick a telescope" up at the top. On that page they have different topics to help you figure out what you want. If the information on the website doesn't answer your questions, they will be happy to help you if you e-mail them.
