1) E-Nights? LOL... sorry, but DL doesn't seem to know what those are...
2) depends on what kinds of prices you want to pay for food. There's McDonald's, Denny's , IHOP, Millie's, etc just across the street on Harbor. Or there's several places that I've enjoyed eating at in Downtown Disney and within the DLR Resort hotels
(Napa Rose for pricier but great food... Goofy's Kitchen for characters with your meal).
3) If you're coming in on the monorail, I'd start off in Tomorrowland with Space Mtn... and then head west into Adventureland to take on Indy, and work your way back into Critter Country to Splash Mtn.
Dunno if Matterhorn will be open when you arrive... it's due to be back open on 12-12 apparently.
