Hi there.
I'm not sure if you've already done the course or not ... but it's a requirement to sit the VI3 Install and Configure course before you can get certified.
You can check out where / when the courses are available here (pricing is in US$)
http://mylearn1.vmware.com/mgrreg/courses.cfm?ui=wwwIt's quite expensive for a 4 day course, but from my 2.x course that i went on, and feedback from people who have sat it, it's one of the better run courses that i've ever done.
If you were already certified in 2.x you don't HAVE to sit the course. I was, but am doing the course next week anyway.
I haven't looked into the exam too much as yet.
As for other study, the official documentation and whitepapers are one of the best sources for study material
