Need Reel to Reel Tape Primer Sources

Where can I learn about reel to reel tapes so I can purchase intelligently blank reel to reel tapes? I've read bits and pieces about tape age, binders, sizes, thickness, Maxcell vs. Ampex vs. Scotch vs Realistic?, Regular tape vs. Chrome-magnetic, metal tape holders vs. plastic?, etc..., but no coherent explaination in one or two places that makes sense. Can anyone point a newbie in the right direction for information and grounding in this new undertaking? Or, share a few good pointers? I just bought a TEAC A 5500. Thanks.
