Hi and welcome to the forum

Sounds like a well loved car and very special.

Have a look at the www.pscan.uk as an upgrade to your OBD2 reader. As an added incentive you can now use it to get a  SAWS Tuning - Custom MG Rover Remaps  in your driveway without removing the ECU. There is a subforum as part of the t-bar at  MGF & MG TF Owners Forum - pscan.uk diagnostic tool - (the-t-bar.com)

I have fitted heated seat elements in 2 sets of MGF seats and 1 set of ZS seats, definatly worth doing and not difficult if you work sensibly. MG/Rover workshop manuals advise disconnecting the battery for 10 minutes before touching any part of the SRS system, including the seat belt pre-tensioners. You will need a T50 torx bit to get the seats out and disconnect the seatbelts from the seats. I got one on a 1/2" socket head from Halfords.

Keep us updated on your journey, and some photos would be nice.
