Boy you have really jumped into the deep end. I actually have a fair abount of recording Native "drums" and its really really tough, but a lot of fun.
If you can I would try and record to multiple tracks so that you can mix down later, since it can be a tricky mix. You basically want to get three elements:
1) a close mic on the main drum to give it a litte extra definition.
2) Vocal mics, These do not have to be individual mics, but can mic groups of singers. If you have some really good mic stands you can put an XY pair of bi directional mics over the main drum to catch the mail voices.
3) Room Mics: Most "Drums" are pretty damn loud and the musicians themselves will do a lot of mixing for you. A couple good mics ten feet away could be a large part of the sound.
and a forth) if there is a leader that is a soloist you may want to give him his own mic.
Good Luck.
