Only Burton bindings can go on Burton Boards(3 screw). All other boards use the 4 screw standard . Included with new Burton bindings are 3 and 4 hole discs so they can go on any board. So if you buy used Burton bindings , just make sure the seller includes all discs.

I'm not sure where you heard that K2 bindings have design flaws, but I wouldn't agree with that at all. Although I ride traditional strap bindings, K2 makes the Cinch which is their take on a Flow styled convenience binding. As for their regular traditional bindings, I would say that it depends on which model you're looking at. All brands make cheap $129 beginner bindings that are exactly that, for beginners.
It is possible for to find reviews about the Burton Mission snowboard bindings, just by going to the site called SnowBoardingsHQ. The site gives all information and detail-by-detail about snowboard bindings.
No some rivers can become wider, smaller, deeper and narrower. not all of them follow the same pattern.
No, you have to use boots specific to those bindings. I'm not sure if you have Clickers, the old Switch step in's or something else but I can tell you it is going to be hard to find boots for them and you need to get rid of them! Step in's are outdated and can be unsafe. Flow and K2 make alternative's to these methods that allow you to use any brand of snowboard boot as well and get the performance and response you need.
