I normally don't use any caps there, but if anything, 10uF FC would be a good choice.

If I'm not using BG caps, Panasonic FC 1500/50 are my first choice.
Is there any advantage using 1500uf/50 vs 1000/100uf on the cap setup?

I am running Mundorf Mylitic AG+ 4 poles for the 1000uf caps on the PSU board and 100uf Panasonic Pureism XPL 100uf on the chip board?

The rating of those large caps is not critical, more important is the type of the cap.
Your setup would be fine.

Should I replace my 1,000uFs FC to 1,500 uFs FC, would I get improvement for my mid/woofer amp (no xover)?

It wouldn't make much difference. If anything, use 2200uF

Pronounced improvement in the clarity.

If you're looking at Audiosector LM3875 kits, don't skimp. Go for the premium kit.

I also added a small subwoofer to my bookshelf speaker setup and it works great to fill in those lower frequencies.
If you want more bass and to keep the freshness, do not replace the caps. Keep the 1500uF on the main board, and put the 10000uF on the rectifier board. One for each rail. 4 for two channels

Solder the feedback resistor (rf) directly to the pins with the shortest possible lead length. Even go as far as to make it a Nude Vishay.

OOOOR call me nuts, but I think it'll help you achieve a less compromised sound.
