The main difference in shorts is in the cut and comfort of the chamois.
As for wicking jerseys and socks over T'
s: Cotton is clammy when you sweat in it, and holds moisture next to the skin. While this feels like evaporative cooling in the summer, in cooler weather it will contribute to hypothermia.
Wicking fabrics "wick" the moisture away from your body which is cooling in the summer, and warmen in cool weather. I personally find it way more comfortable, although some of the fabrics feel slick and icky to me.
Socks - wicking sox will prevent blisters and are coooler. You can get cheap ones at any dept store, no need to spend $9 a pair unless you want to
