I noticed that after this upgrade, the ability to update the VM running Prism Central is now greyed out, as is the Power Off Actions. My instance of Prism Central has 16GiB of memory and is running at 96%+ memory usage. I'd sure like to increase its memory and reboot it via the proper procedure. I SSH'd into the VM and ran top to see the big memory users and the 'insights_server' and a few 'java' tasks are consuming over 10% each.
Has doc been created on troubleshooting PC 5.5 VM issues?

Yes, from 5.5, the ability to update the PC VM from the PE has been disabled. You should though get the option to update the PC from the PC Prism page where you can explore the VM's.
To ensure, the PC is configured with the needed memory based on the VM entities, please run the below NCC check on the cluster,
'ncc health_checks system_checks pc_memory_availability_check'
If you see a 'FAIL', the PC VM needs to be up-scaled.
We would recommend the PC - Scale out feature which is introduced in 5.6 which would take care of the capacity and resiliency. Please find the documentation here, https://portal.nutanix.com/#/page/docs/details?targetId=Prism-Central-Guide-Prism-v56:mul-pc-scale-out-t.html
If the above cannot be considered, then, we will need to bump up the PC memory based on the demand in 5.5.x.
Hope that helps!
