"I am not sure how I want to tackle the right one."

I had success with drilling a hole through the rubber, inserting a hacksaw blade through the hole, assembling the hacksaw and making a slit through the sleeve. Then I used a chisel and a hammer to collapse the sleeve until it fell out.

"Are the rear trailing arm bushings easier or harder to replace than the control arm bushings?"

In my opinion, the TABs are a different beast entirely. The control arm bushings can be done by improvising at the workbench. Replacing the TABs will be very difficult without building, buying or renting the special tool.



Here are some pictures of how I did mine:

Good luck with the job!
