ahhhh My head is about to EXPLODE

SOOOO Much to review & digest, I am on my 4th SBI video day and have been doing my brainstorming/keywords searches etc...
Getting close to putting my content down on paper... I seen on Lisa's flat-stomach-exercises.com a book review as well as other sites.
I do have a book that has been extremely helpful to me and is right on target with my site concept...I have recommended this book a lot on my blog but have NO relationship with the Author.
#1- can I still write a review about his book? (I assume I can)
#2- what is the best way to link it so that if possible I get some type of referral fee...
I do LOVE the concept of being an INFOprenuer and building a site that brings a lot of value to the readers/visitors.
But as U know the hardest part right now is getting it rolling/ at least 10 Focused Content pages down in a good flow and I would like one of those to be that book review? cause it does have a common theme within my site concept.
Any thoughts on Book reviews and best ways to do one? Do I wait or add it on my initial site roll out?
Thanks all,
Bob
