Hi,
Now that you have passed your exam there are several things to be done prior to the CSLB issuing your license. Checking the CSLB web-site it looks like they are working on final fees/documents received March 25,2009.
If you haven't already applied for your Bond you will need a Contractors License Bond and also either the Workers Comp Exemption Certificate or your Certificate of Insurance showing you have Workers Comp Insurance.
Although the state does not require you to have General Liability Insurance it is something you should consider. It just protects you as the contractor if you should accidently damage a clients property etc. It also shows prospective clients that you are not only licensed but insured as well.
I can help you with any of the above mentioned Bonds and Insurances you need. If you have any questions and I can be of assistance please call me @ 1-866-621-0773.
Again, accept my congratulations on your passing of your license exam.
You will be ready on day one when the economy rebounds.

PS You may need a county or city business license. Talk with an accountant about setting up your books.
I hear that QuickPass has excellent software for small business but I beleive that talking with a professional first would be the way to go.
