You don't want a touring bike (slick tires and gear ratios are improper) or a downhill bike (stupidly expensive, overdeveloped suspension), you just want a relatively cheap and conventional mountain bike. Then buy a water bottle, some sunglasses and some biking gloves, and vwala. You can accessorize further or splurge on a 2 grand bike, both make you look like a filthy yuppie.
If you get into it further and want to upgrade, forks, deraileurs, shifters, brakes, etc. are all easily replaceable. In particular a high end deraileur and hydraulic disc brakes are two admittedly nice ammenities that you won't find on a $500 bike but can easily be added at a later date. I repeat the bit about rear suspension; don't buy a bike that has it. Your knees provide plenty of shock absorption as it is as long as your ass isn't in the seat which it shouldn't be on any trail with an incline. Having a soft tail robs energy from your pedal strokes and makes biking harder than it has to be for no real benefit.
