King -
I feel that differences in GAoP vs. F&I, War Revolutionary War period shoes are not that great as to warrant concerned. I'd stick to whatever is commonly available/affordable.
Stockings are available through most online vendors. I'm happy with the light weight cotton as they seem to fit my foot and leg best. Some of the other materials are less forgiving when it comes to leg girth and length. Cotton stockings are available in about a dozen or so different solid colors. Personally I shy away from the stripes. Oh, and don't forget about garters! No, not the frilly ones your girl wears. Many vendors have leather garters with buckles available.
Dixie's QA pistol kit sounds like a neat winter time project.
