15-16 Days of Reserve per month. The line you bid will not have more than a four day block. Can go up to six in month-month overlap correction, though. But you can make one of those days non-RON.

Yes. AM and PM reserves. In my base, AMs start at 0330 and PMs start at 1100

There is only 2-hour call out for reserves. No long call.

Yes, you can bid whatever OT you want and you'll get what your seniority can hold. As a first year, bid OT time trips at straight pay. You'll be awarded the trip over all the dudes bidding premium pay for it and you'll get near premium pay (actually, you get paid second year pay for OT picked up from the company, and that is pretty close to premium).
