congrats for your new conquest :-)
The M7 with a 65 is a great combi. What you should know:

- turn off the main switch in bags
- always take a spare battery with you. The M7 will not release without battery.
- watch the frame counter. There is no lock after 10 pics.
- train yourself to handle the camera without touching the view and range meter windows ;-)
- check if your range meter works correct, i.e. that it machtes the real plane of focus. Take the camera to service otherwise.

Good light!
