Skip the crappie - they're very bad about overpopulating in ponds. You could stock all of the other species you have listed, though you'd want to keep a close eye on the pike and if they spawn successfully you would want to keep all the ones you catch. If pike are your top fish of interest you might also think about stocking some golden shiners as additional forage so the pike (and bass) get bigger. You'll still need bluegill as the foundation of the forage base though.
Also, you wouldn't want to stock more than four or five pike initially, maybe a few more than that if stocking fingerlings but if you stock larger fish no more than four or five; a pond that size can't support many of them.
Actually, if you were to stock pike, you could also stock crappie, as the pike would keep the crappie from getting too out of hand.
