I think you have a solid chance with your ED to Dartmouth, but it is still a long shot for all highly qualified at this level. Your leadership roles with scouts and having a job do help. They read the essays and I am sure those were where you spent a good amount of time since it was your ED.
Your out of state UVA and UNC chances may be tougher than some of the others. I am not sure UNC even cares about legacy.
PC, yes, they are a safety for you. Villanova, most likely. Vanderbilt and some of the others could defer you to RD rounds, or waitlist to see if you are really interested and protect their yield.
