Default balsa wood component thickness

I plan on building a one piece wing as follows

Wingspan= 6 feet
Chord Length= 14 inch constant
Airfoil= Selig 1223

The main spar has been sized and chosen accordingly after determining the moment and shear the wing will experience. I am planning on building a wing with one main load baring spar, and a false spar to assist with aligning the ribs of the wings. The wing will be a semi sheeted designed wrapped in monokote.

I am seeking recommendations for the thickness of the following balsa components?

Front and trailing edge sheeting (provide smooth front and rear surface for monokote to bind to.)
Stringers (placed on the exterior edge of the spars.

I haven't dealt with balsa much in person and I am having a hard time judging the thickness required.
