Todd, the bgills grow very rapidly as do the bass. I put in an IDNR hatchery produced stock (which were free along with Bgills and CC (Need to meet criteria with pond)) of 1-2" LMB last June and they were 7" by Oct. The bgills will spawn very soon and this will give forage for your initial stock plus the the spawn of new bass. It seemed like the bgills spawned at least twice in my pond last year as I saw several sizes of them. It could have been different fish spawning continously? Anyway, the bass will feed on frogs, bugs, and whatever else they can find but you need forage for all the bass when they are big enough to eat other fish, which if I figure right will be in 1-2 months. I'd get em in now. My $.02.
