Well, you know enough to ask relevant questions.
If you haven't gotten the bushing out yet I would seriously consider not replacing it, unless it's really wallowed egg shaped.
Do it when the end plate is disassembled and rigidly support it. You can use a small bench press but make sure the end plate is mounted level very rigid and the bushing starts straight. Go slowly. You will feel when the bushing bottoms.
A bushing driver would be ideal, but if you don't have one you can use a big drift punch or a big flat washer with a smaller drift and tap it in. Make sure you start it straight. Be gentle. If you start it crooked and simply beat it into submission it will deform enough run tight on the armature shaft. It's an interference fit on steroids rather than a press fit.
You can make an adequate bushing driver from a piece of stock with a larger diameter than the OD of the bushing. Use a bench grinder to grind to about 3/4 of the length of the bushing and round enough to fit in the bushing. If you have a drill press you can take it to the "finished" dimension with a file. You will be surprised how nice a fit you can get if you are careful.
Hope this helps.
