1. You would have to look at on what kind of roast and such. And if you really want a fresh tasting cup of coffee, whole bean. Normally I go as far as freezing whole bean coffee (which I was told wasn't neccesary). As for me, in terms of pricing, normally I will just purchase Starbucks packaged coffee. In terms of specialty coffee, can't help you as much there.

2. I had a cup of Volcanica coffee from a friend and was quite surprised.

3. I use drip most of the time but french press for entertaining guests.
