Question about using Canon lenses...

Is there an easy way to use my Canon lenses with my K20D? And if so, will the auto focus work? What if the lens has IS?

This is a commonly asked question, but no. Canon lenses work on Canon cameras, Pentax lenses on Pentax cameras. Some people who like tinkering may have managed to cobble together crude adapters that allow Canon lenses to sort of work on Pentax if you don't need them to be able to focus at infinity, don't need auto focus or exposure metering, and/or don't mind the IQ being degraded, but they generally would not be worth your trouble to seek out.

BUT you can use Pentax lenses on Canon bodies with the appropriate adapter. Manual focus/exposure of course, but LOTS of folks using old SMC-A/M primes on their EOS bodies.
