Does anyone know where I can find a good deal for a cd player/stereo as well as some good speakers that I can put in my 70 el camino -- I'm talking about kick panel speakers.

well... check out

they've been good to me, especially check out their 'open box' equipment, it is stuff that been returned or scratch and dent, but it's in really good shape overall.

As for kick panel stuff, good luck, you might try getting Q-forms from Q-logic, but I'm not sure that they make them for older elkys.
If not, try this link, hope it works http://www.opgi.com/VCProdFrame3.asp?group=21642
Those are kick panel speaks for your car (I think) but the problem with those is that the speakers probably aren't gonna be top quality high-power speakers. (But they will be better then OEM)

good luck
