We're filming tango instructional videos, and are getting ready to do our 2nd batch of videos. Sample video:

Learn to Dance Tango: Beauty and Passion

Right now we are using 1 wireless mic (VHF audio technica), and 2 video camera's (Panasonic HDC-TM700K). We are going to probably add 1 camera to get feet shots, as well as moving to 2 wireless mic's, so she is miced as well.

Any advice?
