Are Legacy SCSI drives compatible with the newer SCSI-2 and SCSI-3 controllers? Can you simply purchase an adapter and plug it in?

Usually, yes. Most of the adaptec family controllers come with both 68 pin and 50 pin header connectors on the card. of course, you'll want to check the specs on the controller before buying.

Assuming the SCSI-3 controller does not have to 50pin SCSI connector and only has the HD68 SCSI-3 connector, can you buy a 50pin SCSI to HD68 SCSI-3 adapter and simply plug it into the SCSI drive and it will work?

The older SCSI devices should work. By using the older devices you may need to avoid using address past 7. The hard part may be finding the adaptor.
