Ralphies murder, Raymond wearing the wire and the Russian are probably the "most" essential to tie up I think.

Yet, for me anyway, although,not mandatory, I would love to see them follow up on Furio and see what happens when/if Tony finds out about Melfi's rape. And I do like the Carm/Tony separation/divorce storyline and would enjoy more conflict before a resolution to that as well.

Like I said earlier, maybe Chase is waiting for the final season and have one loose end after another get resolved. We'll see.
