HS isn’t looking good. I’ve never had a FP for BaTB but usually for shows, the FP window is for 15-20 mins starting 30 mins before the show, so you would miss it. If your kids are going to be in the Jedi Training Academy show, they’ll need to be back at the sign up area 30 mins beforehand. Try putting it in as a break before your chosen show. You need to sign up for the show in the morning. And it takes more like 30 mins for the show. If you’re just planning to watch, you’re fine just turning up a few minutes before.
I’m not sure what to suggest. HS is always a really hard day to plan, though it’s easier for me this time because DS aged out of JTA. Maybe try getting a FP for Frozen instead. Or what about Muppetvision, it’s not on your plan but it’s fun. You don’t need a FP for any of these but you need to use one to try for ASS later. Are you interested in Star Tours? Because that’s a ride it’s at least easy for the software to figure out. And you could always tap in to ride, but not actually ride just to use up a tier 2 if all else failed.
