I have recently gone through the same decisions you are facing. My choice was to implement a solution along the lines of what Uppermidfi has mentioned. I started with all of my components behind and between the speakers, using no ICs longer than 1 meter and speaker cables of 10'. This setup definitely contributed to feedback into the table.
Next I strung out the ICs between the TT, phono stage, pre and amp so that I only had the pre and amp between the speakers. The TT and phono stage where on a heavy rack outside of and slightly behind one speaker. I checked this location with the RS sp meter and there was a null there in the lower frequencies. The feedback situation was better but I was getting a hum in my BAT pre that I could minimize by turning my amp 90 degrees to it and moving it to the limit of the 1m IC between them. So I new I could do better.
I have taken the pocket book hit and purchased a set of 6m Nordost SPM ICs, (got 'em used here on the 'gon). Now I can set the entire front end across the room from the amp. No more hum. My digital components are on a rack with my pre and I have moved my TT to a seperate, light weight table with an extra piece of melomine under the TT. The low frequency feedback is nearly gone and the new table has brought the punch back to the bass. A kick drum now has a snap, not just a thud, and the image is much wider and more 3D. I am still experimenting with exactly where to place the front end pieces. Right now they are on a side wall about even with my listening position but not in the first reflection from that wall.
I would suggest keeping your IC from the table to the phono as short as practical to keep the capacitance down. It is also much easier, signal wise, to run a longer IC from the phono stage to the pre as the signal has been amplified and is less susceptible to noise.
