The only tool he uses is the DynaMesh Sphere. You can find those in the Light Box of your ZBrush Projects file. Or you can have a Sphere on the canvas in edit mode and go to Tool Menu/ Geometry/ DynaMesh and click on the DynaMesh button to change it into a DynaMesh.
He then uses various brushes like the move, standard, inflate, and the clayBuildUp in some areas. In others uses the Move transform tool to pull out shape and make extrusions. These are beginner things and have been in ZB for some time.
He does nothing fancy except makes Poly groups with slice curve or make poly groups from masks. Then uses the Panel Loops option. These things are a bit new to ZB but can be found out all about them on the main Pixologic Site Classroom here http://pixologic.com/zclassroom/homeroom/lesson/panel-loops/ This is actually the model at the top for the over view of these tutorials 
Please check them out they are made to help “newbies”, beginners, intermediate and some advance users to learn how to use new features or learn things you do not know.
I understand where you are coming from, but here on ZB all you need to do is ask and someone will help you more than likely, you are not alone to learn it all without help and usually someone has made a tutorial about anything you want to learn. One thing I love about this place besides all the friendly artists.
Hope this helps you and good luck.
Happy ZBrushing!
