Test Cases, scripts, suites....where to start?

I'm new to RQM and we're trying to figure out how best to implement for our project. We have 3.0.1 and will hopefully be attending some training next month, but in the mean time, is there a white paper or article or someone who can explain the hierarchy between the test cases, scripts and suites? I thought I had it figure out, then I created a test suite execution record and discovered I didn't understand it as well as I thought. I had test cases with multiple manual scripts associated, but during execution, it only took me through the first script and then called it done.

So my biggest questions:
Where do you start? Do you start by creating test scripts or test cases? And why is there a difference?

What's the difference between a test suite execution record and a test case execution record?

I'm sure I'll have more questions later, but that's my starting point right now.
