Congratulations!!
That's a very good book... but like the tutorials it just covers basics...ish. There is LOTS of great information in both, but you won't realize it until you really get into Shake.
There are a few websites that also have some very nice free plugins for shake that will make your life a little easier... especially in the keying world.

Keep a hard copy of the manual nearby.
AND -- ask questions here. Maybe we can bring this forum to life.
