Turn it into a drinking game.
As the game goes on and they get drunker there is a much higher chance they'll get intensely into it.
THIS. We often play DD&D. We often feel kinda foolish in the actual roll playing aspect, so we focus on combat mostly...as a 1st time DM I was able to weave some storyline into the combat, but keeping them focused on the action is the key.
*EDIT*
I recommend acquiring a copy of "The Sunless Citadel". It is an easy pre-made adventure. It was my first introduction to D&D, and that's what got me hooked.

*Second EDIT*
As we are poor and don't have the gumption to get maps and whatnot, we use graph paper and our "imaginations". It involves a lot of erasing, but it makes life easier. I have a D&D 3 ring binder that I use for everything. Also, here are a few sites I use.
