Where do you place your solar cut-off switch, between panels and controller or controller and batteries?
These are two different things.
Controller MUST have a fuse or breaker on the output side.
Panels MAY have a simple switch before controller, not necessary to fuse (usually) and not necessary even to have this switch, it's more a convenience.
See
Diagram on page 19. This is from manual of my controller, diagram shows 2 controllers, ignore the 2nd one.

Anyone use this type of mount to avoid drilling into the roof?
I don't think anybody is using them. Use aluminum. Plastic is not a good idea in sunny and warm climate. Don't see any other benefits, either. Do what other people did, less chances to get it done wrong. On a rubber-ish roof with plywood underneath the only reliable mounting is with both #10 screws AND a sealant like Dicor lap sealant or Geocel Proflex RV sealant. Those are most commonly used, I tried both, they are very different but both are good. With any other sealant you're taking your chances.
On fiberglass roofs people had a success with self-adhesive tape (forgot the name) and/or sealant, without screws.
