As far as keeping the bass you buy on pellets. From what I have seen so far the number of fish per acre has a lot to do with it. The magic number seems to be about 50# per acre. At that rate they seem to be competitive enough to stay on pellets very well. At a lesser rate they will still take pellets they just aren't as aggressive. If the bass you are adding are pellet trained and have never seen live forage then you will need to feed for a few months befor taking this off feed as there is a learning curve that they need to get past before becoming competent predators.
