Is this the pineapple delight in question? If so it's gorgeous and congratulations on completing it!
Between the picture and the chart, it looks as if the numbers you quoted (in blue on the chart) are the number of knit sts skipped as you work the edging. The ch6 loops are used on the rounded part of the scallop, and the ch2 loops used to bridge the corners where the scallops meet in a V.
I didn't see where it said one way or the other about the bind off, though its no real biggie at this point if you have. You can still work the crochet border by attaching with a sc in the last st of the BO, ch 6, skip the number of sts shown in blue and work across the shawl.
HTH, until someone else chimes in.
