In the longer term your best route may be to seek out a training course local to you.
The Firewall Enterprise manual is a good resource for learning the fundamentals and concepts of the product and I'd recommend that you take a look at that. At the very least it will mean that when you ask questions you'll hopefully understand the terminology used in the answers.
If there's anything specific you'd like to ask, we can then do our best to provide you with answers.
