New in JAX

Hello all-
I have recently moved from IL. So far I am just gathering some information, and had a few questions..
In IL I worked as a Police Officer before leaving for a private sector career, I completed the academy and the fire arms licensing course. I do have my Law Enforcement Officer Certification for IL.

Can I use any of this to satisfy the requirement for training?
I know my prints are on file, can they access this?
Anything else you think I should be aware of before completing an application?

Thanks for all of the help, this website does have some great information.
