Go with the GT-7 and the airtronics radio. The best charger out right now is probably the gfx but you are looking at a lot of money. A cheaper charger that is decent is the lrp pulsar. Both of them do motor break in as well.
Batteries: You will probably be impressed with either pro-match or fukuyama. You'll probably want to invest in a nice iron to put together your batteries.
Battery tray: I would consider the novak tray to be a luxury. You could also look into a few integy trays as well. I'm of the lazy type and just use my quasar pro occasionaly to dump most of the charge from the cells.
I would definitely buy a JR R1 over the airtronics. It's a personal preference, but I rarely glitch with an R1.
ESC: You could also consider a Quantum 2. Or, if you can find a good 'ole Novak Cyclone for cheap (50 or less), then that'll be a great control as well. You can run a 9 single in 95 degree weather and still not worry about shutting down.
