Homeowner here - house built in 1996, main panel at service entrance is a Square D QO Load Center QO12L200RB. The panel is wired as "main lug", with circuits in the house being fed from a subpanel.

1. I'd like to convert this to main breaker so that I can disconnect utility power to back-feed from generator. I would have an electrician do the work - I believe the parts needed are just a QOM2200VH 200amp main breaker, and QOCGK2C interlock kit. Is this as simple and straightforward as I think it would be?

2. It looks like the bus bars/rails do not extend down in order to allow more breakers to be added. Could that be upgraded? Ideally I'd like to add another breaker for EV charger, although I could remove my energy monitor which is currently using one breaker feed

If you're hiring an electrician, he will know what to get/do.
