You shouldn't need to change anything in the CS boot screen to get your devices recognised, unless they were actually disabled at some point. As long as the IDs (on the devices) are set correctly and both ends are terminated properly, then the drives should be visible (automatically in the case of a HDD, or once mounted in the case of anything else). Put another way, if you can't see any devices then this is more likely to be a cabling/termination/ID issue rather than configuration of the CS - again, unless the controller or specific devices have been disabled.
As for installing Workbench, yes once the HDD is being seen by the SCSI controller it will appear as a device in HDToolBox ready to be partitioned and then installed on to.
