CA taxes... again

Sorry to beat your brains, but I'm trying to wrap my own around all of
this. I've read many posts on the subject so far and am still
confused.

I'm trying to determine the costs with moving my ship to CA and the
related taxes. I've already been hit by the tax man in my current
state, will have to pay the states Use Tax (unless I can find a
legitimate exemption).

so questions... if I move to CA (and base out of CA, I'm thinking
Crystal currently)
1) Am I going to be hit again by the tax man for sales/use tax?
2) Is this a one time charge or a yearly pain in the a$$ ?
3) What are the current rates for said home base?
4) Will I need any more documentation other than sales invoice and
taxman letter?
5) How does the tax man determine 'fair market value'?

I understand that I need to pay if I want to play, but I'd like to
know how much before I commit to a job transfer.
