The colors on the charts is just one example - use any colors you like. I do recommend to use dark for CC and light for MC, the reverse may look blurred.
For the ribbing, I would do no more than 4-5 cm of 2x2 rib on 64 stitches, and than I'd add 6 st evenly in the first chart row.
The pattern is in pictorial form; everything is clearly charted in full color; there's no written instructions.
30 X 30 = 10 cm in stranded colorwork
