Last month:
Marvel men (Thor, Cpt America, and [can't remember the 3rd one]) met in their own meet-n-greet area in Tomorrowland, at the Tomorrowland Landing store, I think it's called. Forgive me, I'm trying to remember clearly, and I'm tired But, they have their own m-n-g area in Tomorrowland, painted and everything, around the side of that store that's in the middle of TL.
As for A+E, I don't remember seeing a regular stand-by line, just the FP line. Their area in Animation Academy is decked out to look like the great hall area, complete with the "tick-tock" clock from "Do You Want To Build A Snowman?" I can't remember where Olaf was meeting; I hadn't looked for him last month.
My general thoughts/plan for your to-do list: Head to RSR FP at rope drop. Then over to A+E M-n-G for FP (or standby if that's what they are doing at that point). Grab a WOC FP when you are in that area. Then head over to DL, and meet the Marvel men, if you choose.
On a side note, have you considered watching the late Paint The Night parade in Disneyland? It's a fun night time parade. The DL Forever fireworks are pretty neat too (movies projected onto buildings during the show!).
