Lots of great information posted above, I might start a new building sooner than I expected with all the positive feedback.
Anyway, as far as paper stock I ended up using Red River Paper
http://www.redrivercatalog.com/
Various weights of 88 and 60 Polar Matt as well as 47 lb. Premium Matt.
I did a fairly extensive testing matrix of papers and printer settings and ended up with the Red Rivers as the best options for my needs.
To be fair, the owners of Cleaver Models did not recommend "photo papers" for some reason, might have to do with how the papers fold. In any case, I found the quality of the printed image more then offset the corner fold seems.
I also tested, and rejected, the following papers:
Strathmore Bristol 100 and Bristol 2-Ply.
Cougar 65 and 80, smooth white.
Borden & Riley 108 lb. smooth white.
In all cases of side-by-side viewing, the Red River papers held better detail, and gave the best color response, probably due to the brightness.
With that said, there might be a need for the other papers to provide a "look" that the Red River Papers could not provide, but that will have to be proven at a later time.
The other thing I did was to test a line of markers for the edge detail. I ended up using the Faber Castell Piti Artist pens mostly used the gray tones as these pens take to paper very well with minimal edge bleeding.
Like I said in the original post, this was my first building so there was a lot of learning and I suspect I have a lot more to learn. Over on the Clever Models site, there are a few guys who have freely given me a lot of information that proved to be extremely helpful.
