Awesome, thanks for suggestions! I will shoot for low 140s on the pork and then pull and wrap if I've got time to spare.
I've got an Oklahoma Joe's offset type smoker. This guy, in fact.

I was thinking of going with Cherry wood for the pork and not sure what wood for the lamb...
(cherry, pecan, or jack daniels oak chips perhaps?)
