My concern is that if I change to a slicker bearing, I'll have to increase my torsion bar sizes to compensate for that loss in spring rate... and that my present shocks/struts will also no longer be appropriate.
At first glance, it seems that making these suspension changes is an all-or-nothing endeavor (change the dampers, bars, bushings, or keep it stock)?

It5's called stiction and it's not really a problem. yes a mono-ball and has close to zero stiction and rubber the most w/the others somewhere in between, but none are an issue wrt to damping and setup
at the edge a full mono-ball is the most precise and yet is still street able, the regular rubber is the least precise but most of us aren't at 10/10 even on a track day so it's not really that big an issue.
The maintenance hassles of poly bronze and urethane far outweigh any reduction in stiction or increase in precision, more so in street use.
The best all round bush set I've ever used is hd rubber, that includes on my personal cars 4 different 993 setups and 3 different 911 setups
