1) I picked up a 'tri-fold' gizmo, much like you describe, at a local camping good store. It's 'da bomb whenever I travel. Load in a few of those mini toiletries (shampoos, bar soaps, etc.) you get at the Hilton. Leave [whats left of] the wet bar of soap at the campground, break out a new one the next day.
2) Two words: Russell Day-Long. It's not really yer butt, rather the seat. Else get used to tightie whities (real tight) (and a pair of flannel boxers over).
3) Frog Toggs work OK behind the barn door fairing of the C-10, unsure of a C-14. Rain gear is bulky regardless.
4) Pleased with my retired Shoei RF-1000 and my new RF-1100, as long as the top vents are all closed. A bit more noise when open.
5) Spit, or crack the visor open just a skoosh. Nose/breath guard helps too, see Shoei above.
6) One word: Held. Not cheap, but very durable, even after multiple grinds on asphalt (don't ask, unless you're buying the beer)
7) Any tire that doesn't have a straight center groove will go where you point it. Am on my second/third PR-2 (front) on my C-10, 8k miles appears to be expected/average. For a C-10
