Welcome to the sport, PA ---- most of the major manufacturers make short axle, short draw length bows, and as long as you get one that fits you (the guys at the bow shop can help) most any bow will do. I'm partial to Reflex, but some of the guys and gals in here shoot Mathews, PSE, Pearson, and others. It's really just a matter of personal preference.
Now, to answer your other question --- chasin' deer with a bow is a lot different than with a rifle. Some of the basics are the same, like watching your wind direction, hunting where the deer are, locating feeding and bedding areas, etc. But remember, you've got to get a lot closer to kill one with a bow, and in my opinion, you need to practice more with a bow to become ethically accurate. Starting slow, practicing a LOT, and shooting 3-D can help calm "buck fever" nerves when you finally do draw back on a live critter.
