Well, I'd just get the 30mm mount and scope if those are the ones you want to use. I doubt you'll need the 1" inserts, but getting them wouldn't hurt anything if you decided to ditch the scope and needed a mount for a 1 inch scope down the road. Of course--- I'm sure you could always just buy the 1 inch inserts later at the same time as you theoretically bought the 1 inch scope...
The main reason people usually buy 1 inch inserts for a 30mm mount is because they only have a 1 inch scope at the time of the mount purchase, and anticipate moving up to a better 30mm scope when funds will allow it later.
