Welcome to the Carrara Crazyness..

 

Marks Tutorials are great and well worth the price.

There are several tutorial threads here http://forum.daz3d.com/viewforum.php?f=66 (at least 4 sticky threads worth).

This one in particular which has links to the youtube videos http://forum.daz3d.com/viewtopic.php?t=143676 his youtube page http://www.youtube.com/user/CarraraLounge#g/u (under carrara basic training). 

After Marks I also enjoyed the Infinite Skills training, they take different approaches.
