I wouldn't recommend using Neoprene or rubber. Too much energy storage (that's why rubber balls bounce). You'd probably be better off using nothing at all than to use Neoprene or rubber (or silicone for that matter) if your goal is to damp resonances.
An engineered damping material would be a better bet. Something like EAR's C-1002 IsoDamp (their IsoLoss VL would probably be better, but I don't know anyone selling it in small quanities for a reasonable price). Michael Percy sells sheets of C-1002 in either 12" x 27" or 12" x 13" in thicknesses ranging from 0.015" to 0.25". You'd have to cut out your own washers (you could use the steel washers as a template) but you'd end up with far better results than with Neoprene or rubber washers.
If you want to try before you buy, I've got a large sheet of 1/8" thick C-1002 here that I bought by mistake (meant to order the 1/6" thick sheet) a couple of years ago but never bothered to return it. If you'd like, I could cut you off an 8-1/2" x 11" sheet and stuff it in an envelope and send it to you. Depending on how many shelves you plan to include, might be enough to do the whole project.
