1. Yes, as long as you are getting good signal to the receivers, and have your DirecTV account number (from Solid Signal), you'll have no trouble with activation.
2. I recommend using Bishop Tape, which is a plasticized asphault-based sealant designed specifically for roofing. Put a strip along the bolt holes on the top and bottom of the foot, and cut a little X in each bolt hole before you drive the bolt through. Make sure you are hitting the rafters on your center bolts, and use 3" long bolts for those. If you don't use Bishop Tape, you can use Henry's roof tar instead, but it's messier to deal with. Silicone RTV isn't designed for roof work and doesn't seal asphault well, so don't use that.
3. Pro installers do NOT install dishes over the living space (exceptions for when you are using something like a professionally-installed Commdeck). If the dish is installed on the roof, it's only installed on the overhang, and the wires come over the end of the roof, under the eaves, and go from there, either into the attic or along the wall.
4. Ideally, it is grounded outside, before the cables go into the house, but DirecTV allows them to be grounded to HVAC power in the attic if applicable.
