If what you want is a well playing radio, just replace the capacitors. Use an ohm meter to check the resistors as you go; if they are far off in value change them as you go too.  You can get a good parts list with layout of the parts to help identifying them properly as mentioned earlier.  Then you won't have to learn anything right away. You can do that as your time permits.  We can always help too.  I've done two of those and I am finishing a third now, so I can help with questions.

Someone replaced the filter caps already so you need to be sure they did it right when you replace them, otherwise it looks original, which is easier to restore.  You will also have to rebuild the lamp sockets but Ron has a nice write up on those.

Doing it this way won't take as long and you won't loose interest or be overwhelmed.
