That would work equally well.

The switching/trigger circuit doesn't need to use the same ground/earth. After all, an earth is an earth wherever it is. You can ground the 85 terminal to the frame, but as you're so close to the battery anyway, you may as well use the battery earth, the path of least resistance.
Ideally the load fuse should be as close to the battery as possible, so yes, between the relay 30 terminal and the battery.
