Row 6 - p2p - I think is just a typo and should read just p2. The start of the row, before the repeats begin, is p2, k1b, p2 which is also the end of the repeat.
The stitch count will vary from row to row as there are increases and decreases on different rows. Try knitting a small swatch and see if it comes right in the end. The pattern starts and ends with repeats of 6 stitches, so try 24 stitches + 5 and knit up the 16 rows. Save this swatch so that you can refer to it as you knit the border.
