It sounds like what would help you out the most is to contact your local NI Sales Representitive, also called a District Sales Manager (DSM). You can find out who this is and how to contact them by calling NI and just asking for your DSMs contact information.
Your DSM sould be more than willing to schedule a visit with you and could answer all your questions, and would probably bring along some demo equipment and software for you try.
As for your statements above, they seem to be pretty much on track. Looks like you've done a bit of reading.
Again, try to contact your DSM, their job is to help you get what you need and get you started. It's a good person to get to know.
