Rusty,
Start here. http://sheldonbrown.com/raleigh.html and this one might help too. http://www.jaysmarine.com/TH_vintref.html

There should be a date code on the 3 speed hub. Something like 66 3, which would be March 1966.
Do the pedals have reflectors? Thing like that. The above link should answer your questions.
Some close up pictures of the brake calipers, rear drops, and the seat stays where they are attached to the seat tube might help.

Good luck.
