I don't think this was the trio's first encounter with JB. They knew enough about him to believe he was worth robbing. Just doesn't follow that you'd plan a robbery of somebody you've not met before. Also don't see JB inviting a first time customer to where he actually lived.
As far as suspect's statement that he didn't recognize the area -- I believe that was part of the deception he was instructed on by the older suspects. Trio portrayed themselves as victims! J Mitchell said he was advised to lie he was robbed and shot (not at Atera) elsewhere -- area he didn't recognize (i.e., also explaining why he was sketchy on details).
Also, I believe they intentionally went to hospital further from crime scene. Parkland (where suspect ultimately moved to) is the major Dallas County Public Hospital, and closest hospital to apartments which would be logical choice for emergency. Instead, they went to private hospital in opposite direction, and IMO-- for a good reason.
