Please go here:
Click on the "Online Endorsement Application" link in the first sentence on the page.
That will begin your process. You should have your CV put together, yes.
Congrats on passing the SSCP!
As for the validation of your work experience, when you logon to the ISC2 site to set up your endorser information it will explain in detail that you will need to provide official documentation from your employer (HR employment statement on official letterhead) that you will upload onto the ISC2 site.
The validation process, verification of employment, endorsement can take up to 6 weeks, so patience is the keyword, however, ISC2 is very diligent in notifying you when all is complete.
Again, congrats to you.
