Removing the bushings is easy.
Use one of the nuts and bolts that attach the dog bone to the car, and install it, and snug down the nut. Lift up one of the edges of the bushing and give it a few squirts of WD-40 and then with a 15mm socket/wrench turn the bolt a few times spinning the bushing inside the dog bone.
Get you a hammer, and brace the dog bone well, and then hit the head of the bolt with the hammer, and out it pops. Sometimes you can grab it and just twist and pull it on out, other times you might have to get a deep socket or a punch and tap it on out the rest of the way.
For me, I made a jig, and use my 12 ton arbor press. Makes removal and install easy as pie.
Just if your just going to paint these, then just mask off the bushing, no need to remove it. You only want to remove them if your replacing them, or powder coating or even chrome plating them.
