Yes, definitely brakes can drag even if they're not doing it on the stand. I always attributed it to the rim and tire expanding as they heat up, because when it's happened to me it (1) hasn't been intermittent, as flexing would be, and (2) continued to drag when I'd get off the bike and spin the wheel.
BTDT on a very hilly ride. Figured it out on a false flat in the middle of a 15-18% grade. D'oh!
On the gearing, if you're having trouble shifting by feel, make out a gearing chart and figure out what gears on your new bike correspond most closely to the gears you used the most on your old bike. How much difference is there? Where are the big jumps? Maybe a different cassette would make you more comfortable. Any time you shift the big ring it should be a big jump. When you shift the big ring, you'll normally need two or three rear shifts to get one step away from the gear you were in previously. Again, a gearing chart will help you figure that out.
