Regarding patch types:
These are Windows Installer concepts at the root of it. WiX Toolset
provides the tooling for implementing these concepts. So if you didn't find
documentation by WiX that's why. There probably is in some form somewhere
though. InstallShield also has decent documentation and somewhat guidance
around your questions and it should be out on the web somewhere as well.
My two cents: I have taken patching to an extreme level in terms of
automation defining them (code generation) as well as compiling, building
and testing them. I did this because 'requirements' were pushed down from
the powers that be. I learned a lot. However I was eventually able to get
the right people in the same room and persuade that a well defined Major
Upgrade MSI for even small fixes/updates in our situation would be less
costly in time/money/loss-of-sanity, etc.
If your hands are tied and you have to or choose to do patching/MSPs, I
would look into what Purely WiX could do. I never did, wish I had.
Good luck on your decision. It's your foot!
btw, regarding "when I roll back or uninstall the patch some of the
properties don't seem to be getting rolled back to their previous values".
it sounds like you either need to implement that rollback and uninstall
yourself. I always preferred the remember property pattern
