Try you tube or if your interested in ZBrush try pixologic's website.

Are you working on a Wacom Cintiqu by any chance(i saw the on screen keyboard in an image you posted )

I read that you are learning the basics of rigging? not to disencourage you but this book is pretty advanced stuff (multiple rigs and scripts and stuff like that), and it's better to start simple otherwise you'll get frustrated .

Looks good though
