The clips are for drywall. You want / need the mass. If going with a suspended drop ceiling, that's fine. Don't spend money on soundproofing in that case. The drop ceiling will not isolate very much at all.

Not necessarily. Generally the walls and floors are much more absorptive, while the ceiling is more reflective. I'm not an in-room acoustics guy, however that's the general design trend
