For some information on what a bow stringer is and some pictures:

I couldn't find a good pictorial for stringing a recurve bow without the use of a stringer, but MrSelfDestruct's instructions are dead on.
I inherited an old Bear Recurve from my Grandfather several years back, and it had been sitting unused and uncared for over the course of several years. I would recommend before attempting to string the bow that you inspect it for any major cracks or separations of the laminate on the limbs.
Good luck and have fun with that bow. My only other suggestion is to purchase an arm guard if you don't have one already. It's a matter of personal preference, but it does hurt like hell if you accidentally slap the inside of your forearm with a bowstring upon release.
