The MaM series are a 1 day per meeting type of event event. There is around 30mins open practice from around 8/8:30ish on the day of the event only then 4 rounds of qualifying (round-by-round format used) then single finals for all.
I hope that helps.
90% of the field will also be on BB greens all round so you spot on there, the foams you use in them are a personal preference thing.
Use of a generator is fine so long as your careful with it's placement (i.e. directing exhausts away from the pitting area and using the longest lead you can etc.)
What car(s) are you running? We are a friendly lot and I am sure somebody with the same car will give you a good starting setup to work from.
See you there
