I still think Franky will join the strawhats crew. He is now a wanted criminal by the government. We dont know if Paulie is a wanted criminal yet, but I assume not.
Paulie will stay to lead the galley la. He seems like a true leader and everyone is listening to him. So I think Paulie will stay.
Franky on the other hand only have his family, which we dont know if they have a bounty or not…. assuming not.... Then in order to protect them from being harm by the government, he has to leave them. Since the government will be looking for him.
Besides... everyone in the strawhats like Franky... and Franky also like the strawhats. So its only natural for him to join, imo.
Well as for the chapter, I think its pretty good. Garp is most likely a D, he seems kinda powerful and had some connetion to Gol D Roger.
I think its pretty obvious that the person that Garp wants luffy to meet is his friend Coby. You can kinda see the bottom part of the round glasses on that panel. Since coby is there, than the other one has to be halmeppo you can tell by the chin.
I think Garp will tell Luffy and co... their new bounty, including Franky of course.
