Al,
Maybe this would be helpful.  

www.ece.orst.edu/~traylor/ece473/lectures/debounce.pdf

Its a slide set on debouncing pushbuttons that I use in my microcontroller class. 
The target uC family is Atmel, but the code is applicable to about any uC. There 
are easy ways to extend most of the examples to multiple switches with little 
added effort.

Cheers,
Roger Traylor
