Now that I got the phone working, what kind of power supply or transformer do I need for the lights on this phone?

Correct ten volts works great. If you can find a 9 volt wall wart those will work as well.

9-12 volt range. if you have to go 24 volt, you'll have to change out all the lamps to #52A's (24 volt)

Anything over 10 and you risk melting or dis coloring the key holder, and you shorten the life of the bulb.

thats true....but the 52A can work on a 18 volt lead... I have come across phones where they did have 24 Volt bulbs in the keystrip. I think AE was pretty good at using those in there phones.
