Some other tips:
If its a powder day, hike up the Headwall and ski down to Rendevous Lodge. Experience is sublime, if exhausting; I think I posted a pic, in the other JHMR thread, from a bluebird powder day I had there a few weeks ago.
Other runs to try I haven't seen mentioned:
On a powder day, Crowheart, Pathfinder and Big Horn in the Saratoga Bowl off the après Vous lift.
For glades, Moran Face, Washakie Glade and Grizzly Glade off the Teton lift.
Any of the black runs under the base of the Casper quad (Jackson Face, etc)
I love the variety and length of the Hobacks, Lower Sublette Ridge, Rawlins Bowl, South Colter Ridge, etc., but they are all extremely snow and weather dependent (they're down low and SE facing. On a good day, they are everything the Vail back bowls wish they were but never are.
Riverton Bowl off Thunder, and Pepi's Run off Sublette are also worth trying.
Tram is a must on a clear day.
Rendevous Bistro in town is a good bet for a reasonably priced dinner.
For an actual moose sighting, look along Snake River banks on way to and from mountain, and along side the access road to the airport.
Finally, you'll be banned from this board if you don't hit the Mangy Moose after skiing, and pound a Mirror Pond Pale Ale or two.
