wasn't sure how or which pins to do it with.

Pins 1 and 5.

Also I know it is a 5 volt tube
and 14.5 amp.do I really need that much to make it glow?

Yes, you do.

Would 12 volt work?

For a very, very limited time, providing your 12V supply is capable of
dishing out 40A. If it's not, it would either clamp down to the maximum
current or trip the breaker.

If all you want to do is make it appear that it's glowing, build in a
few LEDs into the wood base. None will be the wiser.
