As Classic Knuckles was not present in the game because Sonic CD was before Sonic 3, I can imagine Classic Sonic, Classic Tails and Classic Eggman comming from the same time as Sonic CD was as with Generations both games are heavily influenced by time, kinda like how magnets attract one another. While Tails wasn't in Sonic CD, he is now. As for why no Classic Amy I dunno.

The fact he is a bumbling coward would make him ideal. I can imagine him doing some grunt work for Dr. Eggman like perhaps serving as sub boss but I can also imagine him not afraid to say his oppinions on Dr. Eggman, like how much of a fool he is or stupid his ideas. It can work as a good comedy duo between the two.
