1. I think ZZ would suit you just fine and if you don't think CFOP is interesting, I wouldn't do it at all. Cubing is supposed to be fun isn't it?
2. In my opinion, I would switch over now just because the sooner the better.
3/4. All my advice would be is just taking as much time as you need to plan EOLine as you need to since if you screw it up, you will get pretty disorientated for the rest of the solve (as you probably saw in your 50.15 solve). Other than that, just take your time and have fun with it.
