If you're more of a hardware then a software guy, note also that there are some special made IC ta manage switches. Chech the MAX6816 (singel switch), MAX6871 (dual switches) and MAX6818 (eight switches) from Maxim. The MAX6818 also has a "change-of-state" output, that can be used as an interrupt, so you don't need to poll your switches. And the interrupt output is pre-debounced and "clean"... Just a thought...
