Stamos,
Based on what I know, you should be in very good hands with Dr. Shapiro. He was on my very short list of docs that I considered, and still may go to him for some finishing touches.
Unfortunately, your pics are not high enough quality for me to give you an informed opinion about your needs. My general advice would be to remove any obvious/obnoxious plugs in the hairline and/or crown(rather than just trying to camo them). By obvious/obnoxious, I mean pitted or directionally challenged. Also, focus on softening things in the hairline to obtain a natural apprearance.
Regarding the donor, I would use the exisitng scar. You will probably be able to revise this scar while getting an adequate amount of grafts. Importantly, you must lossen up the donor area with exercises. You need to focus on this over the next month.
Finally, this is probably not what you want to hear, but you must be patient. Based on your pics, and depending on your reasonable goals, you will likely have to undergo at least two procedures, especially if you are going to have any pluggy grafts removed during this procedure.
I wish you the best, and look forward to seeing your progress and results.
