I have the kadet Sr. wing halves frames and pined to a wall so they don’t warp.

pinned is good.....to the WALL??? or to a piece of wall board?

I laid the fuselage prints out and ironed the creases out. Is this proper?

yes, then clear cover them so's you don't glue stuff to them

I started studding the plans and noticed that some of the longerons are marked ¼ x1/4 spruce, some are labeled ¼ x ¼ balsa and others are not labeled. Do I assume that the ones not labeled are balsa?

studding=? framing?
front to back pieces are probably spruce, vertical and cross-wise pieces are probably balsa. the not labled ones are probably assumed to be the same as similar ones that are marked on the plans. make sure you're making a left and a right side....don't ask why I say that.

My last question for tonight is, when forming the bottom longeron front do I let the balsa dry before I glue it
