Once I get the bearing out of there, what numbers/marks/etc do I need
to get from it..

The ones that are written on it.

.. and who's a good place to get a new one from?

Your local bearing house. Look in your yellow pages and find 4 or 5 local
bearing houses and call them all every time for pricing. You'll soon see who has
good pricing. I buy bearings and belts locally unless they are something
special. For specials I look on line.
