For (1), No, your luggage will be checked through. For (2), Probably not. You usually get both boarding passes at your initial check-in, even if that is online. Rarely, you will not have an assigned seat on the second flight, and the pass will direct you to see an agent at the connecting airport. In no case do you have to exit to landside; Doha's website says every terminal has a Transfer Desk to handle boarding pass re-issue, as well as missed flights.
