I guess you basically need a drum software plugin like Battery or some version of Drumkit From Hell and a MIDI keyboard to connect with it.
Like here:

Then you can assign keys to the drum samples and play and record on the comp.

There's one called Band In A Box, but I don't think it comes with samples. I think it's all MIDI instruments, so the sound quality won't be that good. Haven't tried it myself, but I did participate in a Jam at the ADA forum last year where one guy used it as his backing track, and it sounded like a $50 WalMart keyboard rhythm track (drums/bass).

Other than that, all I can suggest is FxPansion BFD2 for drums and doing your own bass lines. BFD2 has tons of preset patterns, and you can tweak the drum kits until your head explodes. It's also got a built in pattern builder that's point-n-click.
