I have several motors from old steamers from the 50's and 60's. The older motors have larger magnets; would this make them "better" than the "newer" ones? Assuming everything else is good.

Well....That's a tough one. Newer engines are always more advanced then older engines but that doesn't really mean they are better. If the magnets are larger I'd imagine that it'd be better.

Not really. van motors have magnets that surround the armuture, brushless and cheap. I say hold onto those old Pittmans and so for locos of age. I have 70's steamer remotor'd and the tank engine pulls more cars than it did before. Re-magnetizing helps even more. Haven't tried it.

That depends on the quality of the motor, and whether they have lost any magnetism or not. A weak magnet will make the motor weaker, and cause it to run hotter and draw more current. Open frame motors, even good ones like the DC-70 Bowser used in its steam kits, have a higher current draw than can motors. Cans are more efficient because the magnets are molded to fit around the armature, instead of relying on steel pieces to conduct the magnetism from the magnet. The can may also concentrate the magnetic field.
Replacing the original block magnet in an open frame with a stack of rare earth magnets can have amazing results, and is an easy retrofit if you have an older engine that you want to run better, but don't want to spend time fashioning a new mount, installing a gearbox, etc. I did this to a Mantua 0-6-0, and the performance is about the same as the Helix Humper can motor I had tried in it before.

Are there any neodymium motors out there? I know that they use this type of magnet in earbuda and newer headphones to achieve amazing results.

Sure are. Just for an example, search Ebay for: neodymium motor.

I guess you mean magnet replacement? That topic has been discussed before:
