controlling rgb lights on an arduino via max msp

Hi,

Do anyone of you have experiences with controlling LED lights from max msp to an arduino?

I guess I should use the serial object somehow ...

I have the following questions:

1) which arduino to use?
2) which arduino tutorial to do first to get the necessary knowledge?
3) how to use the serial object in max to send rgb data to the arduino?

Thanks for your help and advice!
