OK, yes right side (RS) or knit rows for your pattern start on the right edge of the chart and read to the left. Wrong side (WS) rows read left to right on the chart. Start the pattern at the right edge of the chart on row one (knit row). Keep repeating from the right side of the chart until you finish row 1 (row 1 is all the same and really has no pattern anyway). When you turn onto the purl side, you'll start at the line for sizes 1 & 2 and read the chart left to right. When you get to the end of the chart for row 2, go back to the left edge and repeat the chart for row 2 until you finish your sts. You can check that you're getting the pattern correctly on the following rows by making sure the stitches are lining up correctly.
The stitch repeat is telling you the pattern repeat for this chart. The chart is actually showing you two repeats.
