What else are you doing in the evening? TSMM becomes a walk on near the time people start to go into fantasmic to get their seats but early enough to ride it once or twice and get into the middle for fireworks (which lately I'm finding very possible to do because once everyone stands up, half the middle of the "hub" becomes empty, and it's the back half with a better view. People just sit down on the ground for a long time waiting for it to start so they take up extra room until someone comes by 10-15 minutes before the fireworks to get everyone standing and move forward.. It's my favorite see it from a good spot trick these days (including getting a tsmm ride about 30 minutes before the fireworks start).
I would try to get a fp+ for TSMM, RnR. The last one I would probably do Star Tours instead of ToT because I'm also seeing ToT near dinner time become a short wait lately. Basically get your list of what's more important and try to get them..
Also to note, if your going to be heading there soon and not preplanning your fastpass, once it hits noon, keep looking for same day fastpasses, they do open up but keep in mind what else you want to do at night because sometimes you get excited and pick one the same time as the night entertainment without noticing.
