Hi Navrig,
My suggestions won't be much good to you tight away on this tour. They may be helpful when you get home, review everything, and later plan another tour.
This is what I use on the kickstand/wheelflop/unwanted rolling wheels cluster. All have been tested on my Raven over eight seasons, and are now part of my kit for the Mercury Mk 3 which has replaced it:
1) Kickstand: I use this instead:
http://www.click-stand.com/ The click-stand I use has four segments, which gives me a folded bundle slightly longer and more slender than the 5-segment item. Depends where you stash it -- mine goes into my Revelate medium frame bag.
2) Wheelflop: I use a QR rubber tie, 6". Dead simple, light, cheap, functional. Here's a photo:

(They're used in agricultural settings, esp gardening & vineyards.) If you want one or two and can't find them, send me a PM and I'll send you a couple by post.
3) Rolling wheels: Click-stands come with temporary wheel lockers, but they don't work very well. Here's the preferred item:

Hope this is helpful in due course.
Safe journeys, John
