Welcome to the forum! I'm kind of new here myself, but I do have experience getting old stuff going.
Johnny's got some good advice. Here are some other things I've noticed on my '46.
If it's been sitting for a long time with gas in the tank, you may need to replace any rubber fuel lines you've got. (and don't forget to drain all of that skanky rotten gas out)
A tip to check the fuel pump (if you have a floor starter) is to crank it without the key being on. If she squirts, then you're probably good to go.
I had to take apart my carb and "degunk" it. That might be a good idea if you can't get it to fire.
Check the distributor. You'll probably have to put a new condenser on if nothing else. Check that the points and the rotor are still good. You may need new plugs and wires.
Check the generator. If it seems deficient in charging, you'll probably need to clean up the armiture (that copper thing on the butt-end of the innards) and the brushes (those little black things in the clips that touch the aforementioned copper thing). Use a VERY FINE grained sandpaper, or go to an auto parts store and ask for generator cleanup strips.
Chances are that the transmission is going to be different than any other you've ever driven. The first time you put it into gear (after checking that you've got enough 90 in there) ease up on the clutch until it starts to engage and hold it there until the engine recovers (1-2 seconds) and then ease it out the rest of the way. If you pop the clutch, she'll stall on you. And don't bring it out of first or second (depending on how many speeds you have) until you have brakes. Reverse may be a little stiff.
Let us know how she runs once you get her going!
