Congratulations Keith,
You might toss in a spare modeling lamp, flash tube, and any associated fuses if the AB’s have them (didn’t look like they used fuses to me and I didn’t see any mention in the replacement parts). When one of these goes south during a shoot you will be glad you did.
You might also want to consider a couple of mini boom arms for your straight stands if you can’t get good angles with your shoot-throughs and softboxes. (Could probably be a wait-and-see proposition).
Definitely at least one long boom arm for what you are planning to shoot to get some light overhead (portrait, macro, product).
