" how tight (or not) should the drop link bush be on the attachment bolt on the lower wishbone ?"
Not tight at all, on the shoulder of the attachment bolt, otherwise you will introduce a LOT more roll stiffness into the front end, increasing understeer. The bushings should PIVOT freely on the shoulder of the bolts, even if you have to ream them out to fit. Lube them also, with chassis grease, on assembly. I had to do this recently with my son's GTV 6, thanks to some incorrect bushing ID dimensions. Locknuts will secure the links in place, with no need to torque them down and lock up the assembly!
Yes, the bushings must be pressed in and retained tightly within the drop link holes, but the entire front sway bar assembly has to be free to pivot and work as the chassis rolls from side to side. Sway bars are best removed/installed with the wheels on the ground, and the chassis loaded normally.
