Can't comment on the front bushings but I replaced the stock rubber bushings on the rear sway bar with poly a year ago.......should be the same process though.
The poly bushing do have to be pressed on (just like the stock rubber bushings) I used a vise to get it started and finished off with a hammer to get them the last 1/4".
After getting the top and bottom links pressed together the links could be moved easily but did have a some resistance. That's the beauty of the poly bushing install.......you don't have to worry about pressing on the bushings at a specific angle. Well along with never having to replace them again.
