Pretty accurate info. But line holders, while many lines do have between 12 and 18 days off, are still only guaranteed 11 days off. So there are some lines with only 11 days off.

Commute out of SAN depends on where to. I think the flights out of there to DFW for example are usually quite full. Commute to LAX is easy, but as has been said, you probably won't get it anytime soon for a base.

JM pay is 150% of your regular hourly rate, meaning if you are drafted to involuntarily work on your day off, you will get paid at that rate. They can JM you so you have only 8 days off, but then must give you those days off back by the next month. And you get to choose which days you want off in that case. If you are JM'd on a day, but want your day off back in the same month, then sched gets to pick which day off you get.

Eagle probably has one of the best reserve systems at a regional. You can "proffer" for open trips on reserve, and can check where you stand on the reserve list for any given day, to have an idea of the likelihood that they will call you. Reserve used to be better before the last amendment round several yrs ago, but some of the reserve rights were given up in exchange for other things (like 100% line guarantee and 75% deadhead pay).
