I recommend to anyone looking for dance resources to visit Henry's Hotlist, a compendium of multiple pages of dance links to different forms of dancing.
http://www-zeus.ncsa.uiuc.edu:8080/~hneeman Henry spent several long years in grad school compiling this resource and perhaps that time spent might be vindicated by the number of hits his site can get.. ;o)
For places to dance in SLC, look at this URL.

Good luck and enjoy.
