Are you really going next month? Good luck!
I'm not sure it's worth getting a dynohub at this stage - is it for lighting, or charging devices, or both? If the latter, then you'll need either one of the B&M Luxos lights which has a USB output from the light, or a thingamajig to convert the output from the hub - such as the B&M ewerk. It all adds expense and complexity, and all the systems have a bit of a learning curve and need some bedding in.
Are you actually going to Russia? Your route suggests Kyrgzystan, and the two most commonly-ridden routes that way are both through Turkey (interesting stuff happening there at the mo, though not on the same scale as Ukraine), then either the unreliable ferry across the Caspian to the flatlands of Kazakhstan, or through Iran and Turkmenistan.
Wild camping along the Danube is dead easy, though there are campsites even when you get further east (most cyclists on it don't go farther than Bratislava and Eastern Austria). Watch out for hunters - I was camping in the woods in Hungary and started hearing gunfire, so I crawled out of my tent to try to let them know I was there, then another shot cracked out, a dark shape in the trees slumped down, and a hunter walked across to drag the deer's carcass away, offering me a disgusted look and some muttered comment in Magyar as he passed.
