1. I watch the original footage by connecting the AX100 to the XBR65X900A. I also have a Mac Mini connected directly to the Sony 4K TV by HDMI but the video drivers only goes to 1080p, so no 4K there. My Macbook Pro does have 4K 2160p outputs to the Sony 4K TV but at a lower than 30p cycle, so it is not useable for Final Cut Pro X editing work.
The video picture to the Sony 4K TV is better when connected with the AX100 than with my Macbook Pro. I hope this is a driver issue, to be fixed by Apple or Sony later as more people uses 4K 2160p.
2. This has been a big issue.
The FDR-AX100 uses is stored as MPEG-4 with a codec of H.264. This is ideal for Youtube 4K.
A 19 seconds worth of 4K 2160/30p video is about 143MB.
But we need to edit for length and add text. Once FCP-X starts to transcode, any of the Apple ProRes 422 formats increase the size to enormous amounts.
That 19 seconds become 1.2 GB with Apple ProRes 422.
I start filming Grease in early April for art schools. I may have to rethink about using 4K or not.
I certainly do not have the processing power for anything for than 5 minutes of 4K footage at the moment.
Even storage will be a concern.

Obviously you could connect a computer directly to the Sony UHD TV, which is what I'm assuming you do.
Second, regarding editing on your Mac, are you using ProRes 422 and if so, how are you handling the file sizes for larger projects?
