Q1) when cabling, is the color order important? like:

straight cabling:
A side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown
B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown

could be eg.: like this??
A side: white-orange, brown, white-blue, green, white-green, blue, white-brown, orange
B side: white-orange, brown, white-blue, green, white-green, blue, white-brown, orange

Q2) again cabling.. i know what is the color order of straight and crossover cabling. BUT: what are the color orders, when i need to create physically two separated networks?

A side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown
B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown
----------
568A; crossover; nic to nic: [it's not so important about from ~2005]:
switch the pairs: 1&2 with 3&6 on one side:
A side: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown
B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown

----------
one cable, two crossover networks:
