Bendy keep in mind that you are talking about the minimum requirements for the program.
Other upgrades like element and formation lead, IP and EP are probably going to put you in better running than a basic AC.
Not a problem on AD. I'm not PACAF so I can't speak for them. But I have yet to stop deploying since I started flying the Herk. Hours haven't been a problem.
Very good for a rough wag. Upgrade depends on a number of things. Is the CC comfortable handing you the keys to one of his jets? Is it your turn to go in the rotation of CPs? Is your coloring book done?
The normal range I've been seeing is 600-800 hours and about 1.5-3.0 years. It depends on the person, the unit, and a bunch of other factors.
