Yes, I finally figured out all of the above (awhile ago). Now I am wondering, since it has never been answered, if there may have been a summons so to speak for the P team to join the Baez team in FL. When LP realized that KC was as guilty as sin, he reneged which is causing all of the confusion because JB considers them part of his team.
I think that it appears as if the P's did some security work out of necessity for themselves. I don't think they were actively security people for the A's; they were just guarding their bounty. That's not confusing to me at all.
Remember the pizza that LP said was delivered to the house and everybody was invited to take a piece? LP said that they assumed it had been ordered by someone within the house. It turned out the pizza had been sent there and they already ate it. That would be unnerving to say the least. So, yes, everyone was interested in their own security.
