wow. finally something i feel i know a lot about to help you guys out. i enjoy hearing all you know about WDW because i've only been there once, but i'm going again this summer. but i am a DL expert if you don't mind me saying. although, i haven't been down there since disney cali has been around yet. so sorry, can't help you there.
the must-do's are: indiana jones - the best disney ride ever!, pirates, space mountain, and haunted mansion. these are all better here in cali. i like splash mountain and big thunder too, but i think they're better at WDW. you will definitely be able to do everything in two days. but i recommend you use fastpass whenever you can. also, check out the walk through sleeping beauty castle. the entrance is at the fantasyland side of the castle in this really small door by the princess store. it says sleeping beauty castle i think.
um. i agree. the blue bayou is a great place to eat. also, try the clam chowder at the cafeteria in new orleans square. and the mint juleps there are delish on a sunny california afternoon.
fantasmic! is not to be missed. i hear it's different than the one at MGM, but i haven't seen that one yet, so i can't tell you which one is better. if you want good seats, better sit down at least 2 hours before. it is awesome i assure you.
anyway. i hope this helps at all. have a great time!
