There is a seat layout for their proposed configuation of the 340-300 on page 56 of this document.
I don't know if anyone can tell where the crew quarters are, but as for as pax seating, it's pretty obvious they plan of 42 Envoy and 227 Coach.

If you take a close look at it you can tell it is the seat map from the original 330 configuration. They have a cabin divider between rows 1 & 2, and 2 rows of business behind 2L.
Another great job by the folk at Tempe!
