For CD play, use the two outputs on the CDP to feed a signal to both systems. For the tuner, use the pre-out's from the receiver to feed the integrated amp.
Ideally you'd like to keep the speaker cable lengths the same in a two-channel system, but I once (out of curiosity) used two runs with about 15' of length difference and didn't notice any problems.
My understanding is that the tuners on most receivers today are of very marginal quality. There are quality tuners you can buy today, however. But to answer your question, I believe the older tuners you mentioned really were better than the ones being made today. Not my area of expertise, however, just my "sense."
