First off I highly reccommend to BUY 3d gamestudio, second, read the manual because you will have to learn how to code stuff I my self down't know how to code but I'm inching across the WDL manual , if you have no prior experience don't rush through the manual!!! because I did that once and forgot stuff instead I make sure i know the concept!
To make the particle effects you could use joshua's particle system simulator it's not eenough for most effects such as swirling and stuffs, to make him morph you could have two player models, one for the human and one for wolf then just morph them through WDl code
All that AI is going to need programming and most people don't give away code (especcially AI) if you want complex characters and stuff learn WDL ! download the manual
