Any recommendations for hikes, good food and wine for a long-weekend trip?

Delaplane is a beautiful area it has great wineries and beautiful countryside especially with the leaves changing. I would recommend Barrel Oak Winery which has great outdoor seating, yummy wine and good snacks. Sometimes on the weekends they have live music. There are also a number of other wineries around the area too. I have been to few but like Barrel Oak the best. I would not recommend Three Fox Vineyards for wine wasn't good but it does have nice picnicking grounds and activities like bocci. I also really love  Hollin Farms where you can pick your own field greens and other things they just had pumpkins. Both are nestled in the blue ridge and not terribly far from  Shenandoah Skyline Drive There are multiple places to get on to skyline drive so there is a closer entrance near Delaplane. 

Here's a list of wineries close to Charlottesville. Barboursville Vineyards is probably the most recognizable name in the area - the grounds are neat, but it tends to be crowded. DelFosse, Prince Michel, Horton (try the Norton!), and Blenheim are good options.

If you guys haven't been to Monticello, I'd make a point to visit, along with taking a walk around UVA (check out Edgar Allan Poe's old dorm). Shenandoah National Park runs along the mountains to the west, and has hiking trails of varying difficulty.

If you want to take the scenic route between DC and C'ville and really want to splurge on a meal, then make reservations for The Inn at Little Washington. In Charlottesville, C & O Restaurant is supposed to be good.

C'Ville is a mecca for restaurants.  Dining out is very popular.  Call ahead to check for seating. There are so many great places, but I know these are good.
