Questions on re-organizing my shares to allow for hardlinks

I currently have my individual shares set up under /mnt/user/ which I set up a few years ago now following people like Space Invader One however as I am now coming to set up sonarr and radarr I'm discovering hardlinks and why they are more optimal. So I'm looking into switching to using the following structure for my shares /mnt/user/data/ I have disabled all my dockers except for krusader which I will be using to move the files however I have a couple questions before starting

1 My unraid server consists of 3 disks (2 for data - Disk 1 and Disk 2 and 1 for parity) plus 1 small 500GB cache SSD. My files span both hard disks, I don't keep files of certain types to one disk, should I be aware of anything before I begin the move process?

2 Will I lose my Plex data (manual sorting, changing of art covers, etc)? I have downloaded the preferences XML from appdata but having looked at it, it doesn't seem to contain much in the way of organizational data. I disabled 'Empty trash automatically after every scan' as was advised from what I've read on this and I won't be deleting the appdata folder or moving it so am I right in thinking after moving over to this new share structure, pointing the plex docker to the new locations and re-start Plex docker everything will remain the same?

3 I have different split levels for some shares, how or will it be possible to keep these when moving to the new structure? As far as I can tell, only the root share can change split level which then applies to all folders created within it
