Forget resistors for now.
If you have not restored any tube electronics before, I recommend setting the TV aside for a while and practicing recapping on a cheap 5-tube radio. TVs have higher voltage and they are more complex, meaning there are more places to mess up if you're careless.
The Sams service manual for your TV is available here:

Some public libraries have Sams manuals, so check with your library in case they can supply a free copy.
Before replacing anything, I would clean all of the tube pins and sockets, as well as the controls (volume, etc.).
When you're ready to tackle the TV, begin by replacing the electrolytic and paper capacitors. This article has basic information about that:

If your TV basically works, it should work just the same -- or better, we hope -- after you recap it.
Check off each capacitor on the schematic and parts list when you replace it. Try the TV after replacing every one or two caps; then, if you make a mistake, you'll know where to check.
If you skim a couple of the TV articles listed on this page, you'll get a general idea of what's involved in making them safe & reliable to play:

Again, a TV is not a very appropriate beginner's project. If you don't feel up to the challenge, you could contact an area radio/TV collector club to see if anyone there is interested in mentoring you or providing some tips. Here's a list of clubs:
