The Raleigh Pros were good, desirable bikes. I have a 69 and a 70. Sounds like yours has been changed a bit as they came all Campagnolo, typically high-flange hubs with a Brooks seat, 3ttt stem and GB bars. Other than typical metric sized wrenches and a few allens, you will need some specialized bicycle tools to work on it: headset, bottom bracket, pedal, and cone wrenches, crank puller, third hand tool for brakes, and a wheelstand for truing wheels. All worthwhile investments if you plan to work on bikes.

A good source of tools/basic parts is Loose Screws: http://www.loosescrews.com/index.cgi

As you start riding, take care not to push too high of a gear; learn to "spin" (pedal somewhat rapidly, 70-90 revs a minute or so) and your knees will love you. Start short and increase the distance every few days. Just keep it up and you'll do fine! Good luck.
