Noble Endeavor. I love shopping for guitars. Go to every guitar shop you can find and just sit there and play. Guitar Center has a great selection. Play some high end Taylors, Gibson, and Martins. Once you get a feel for the sound and playability then start pulling the lower price models off the wall. Solid top would be a must for me, but after that it's a lot of personal preference. He more you play the better you will get to learn what you like. Pay attention to the wood used on the back and side in relation to which guitars you think sound the best.
In the end guitars are really a used market. Buying a new guitar is really only a protection against a novice getting something with a defect. Old guitars sound better and are cheaper than new ones. Thus if you know what you want then don't be afraid to venture into a used guitar. Just play it first or have a return policy.
And again, enjoy the hunt. Not many purchases where you can walk in, play $30,000 worth of merchandise and walk out without spending a dime. If you feel guilty buy a pick or a set of Eliixr's.
