Less than 1 hour if you have the correct tools discussed in this thread, and the head of the tensioner pulley bolt is not broken off.
1. For tensioner, you do not need a security/tamper t60 bit with the hole cutout in the tip, regular t60 is ok.
2. Does it matter if the t60 bit is a two piece design? Probably not, so long as it's strong enough.
3. When routing/reinstalling the new belt, can the entire install all be done from the top of the engine, or do you need to also raise the car, and remove the under tray to have access from underneath? On N52, all can be done from above.
