Trying to understand and learn LavishNav

[aChallenged1]

I want to start out figuring out the following, and how to do it...
LavishNav

I found a helpful bit of information on creating a new LavNav file over on ISMods (post HERE)

Anyways, this is what I want to start with. It is no small thing, but it can be done bit by bit adding as I go. If I can get this working in one area, I can start making regions and paths anywhere I can travel.

What to do:

Define region for Khal Crafters Hall, type: rectangle.
Make it encompass entrance and hallways as one sub region (also rectangle).
Make it encompass the hall itself as another sub region (again, rectangle).
Define areas to avoid (e.g. the big wheel on the floor, and other places that will cause a character to get stuck).
Define box region for the two vendors.
Define a rectangle region for Baasa encompassing his walking path and his end points (refining TM).
Define a region (not sure of type yet) for Kiaravan, his path and points (finishing TM).
Define regions for the various trainers.

Create points for pathing, especially in hallways, through doors, etc.

That's the start of what I want to do in my attempts to get to where I understand LavNav. Any help from anyone who knows what they're talking about concerning LavNav is welcome. Lax has tried, and eventually I'll get it. It just takes me time.

Key
Light Green (around everything in general) Top level region, everything else is a sub.
Brown: Khal's Crafter Hall (will have to break into at least 3 parts, the halls and the main hall) these are the first sub regions.
Grey: crafting tables (missing some, doing from memory)
Blue: pathing for refining and finishing taskmasters, these would be their regions, where you would look for them.
Other blue: Outfitter trainer and another. I'm missing a few, I know, but this is a work in progress. Each trainer, or set of trainers if near to one another, will be a separate region
Bright green: vendors region.

Now, how I make this happen, that's what I'm going to be trying to figure out.
I'd have linked it rather than uploaded it, but I don't know where I could do so from (I don't like most of the free picture link places).
