Hi Joern, If it is an option: use Leerrohre (DE for "empty tubes" ?) to make it future-proof, rather than to rely on cable-standards. In a few years you may want to replace coax with optical or whatever.
The only question I can answer is #4: The problem is reflections caused by skin-effect if you do solder them. Back in the days that I spent in the physics dept. we used solder-less crimp connectors for everything high-freq.
