ftf,
The basics of a good campsite haven't changed since I was a Boy Scout back in the last century...
~ a relatively flat and level location for comfortable sleeping, 
~ the fewer rocks under your sleeping area the better, 
~ an area with good drainage so that it doesn't get soggy if it rains; a lsight rise is a good place to get this feature,
~ some kind of natural wind break like a cliff or row of trees/treeline or hillside/ridge to keep the wind off of you,
~ an easterly facing site will give you the sunrise in the morning and help dry off your tent during the morning,
~ near a water source is always good; a spring, stream, lake, snowbank,
~ a soure of firewood if you are building a fire; use the rocks to make your fire ring and something to sit on.
Things to avoid include...
~ areas with lots of poison ivy and such,
~ low areas since rain will accumulate there and cold air settles there at night which makes for a cold nights sleep and dampness in the morning,
~ any place with widowmakers in the trees; these are broken branches which might fall on the tent during the night or on you as you walk around the campsite, I set up at dusk one evening and awake to find a six inch thick branch hanging over my tipi tent... I shifted position rather quickly.
~ anyplace near something tall on a ridge or in an open area if lightening is in the forecast.
Hope this helps.
