The raspi's GPIO is not enough?
Is the arduino still needed?

I do think so, because precise interrupt handling is needed.
Also (even with an arduino) don't expect a very fine dimming: 100 different values, linearly spaced between 0 and 100%, reading the firmware they provide, sketch #4 ; better firmware is possible though, but quite a hard work...

One or the other should work. If you can run Pd on the pi it would be even better.
