I think most people will feel safer advising you to go the same route they went (its hard to tell someone to do something you've never done. hard to be honest about it, anyway), so I would take all suggestions to heart.
I'm sorry not to have a suggestion for you, but I've been thinking about a LF ever since I used one in a studio.
The only thing I can suggest is for you to go to a bookstore (or library), sit down and study your favorite photographers. I've done that (and still do from time to time) and it helps tremendously.
