If you want to do some drinking - you have to go to Epcot and attempt to drink around the World. Even if you don't complete the attempt (11 countries and above average prices on drinks), you can easily have a blast touring World Showcase.
Disney Springs (nee Downtown Disney) has some great spots - I recommend Raglan Road - especially if you like Irish music.
For rides - pick anything. If this is your first trip, everything will be new. Any of the Mountains at MK, Jungle Cruise, Haunted Mansion, 7DMT, Test Track, Mission Space, Soarin at Epcot, ToT, RnR at HS.
If you guys are golfers (or like mini-golf), the Fairways course at Fantasia mini-golf is pretty challenging.
Back over at Disney Springs, Splitsville on the West Side would be right up your alley (pun intended). One part Bowling, one part restaurant, one part club. Seems like a really cool place (walked in, didnt have time to bowl or anything else).
If the weather is warm enough, try the water parks.
Hope you have a blast.
