I usually set up bipes with equal incidence top & bottom but I know some folks like a little convergence (e.g., lower incidence on top).
On a biplane, the top wing has the most incidence, not the bottom. Also, the neutral point is 23% MAC (equivilent monoplane, including area weighting) for biplane wings. I wouldn't do the droop at all, keep it straight, thats my opinion.
I would like to see your spreadsheet, I'm always interested is seeing what other people are doing.

I always make the lower wings 'stall' first (unless they have the ailerons). Prolly makes no difference since we aren't inside the airplane to feel the buffet before the wing lets go! RC fliers are more retroactive than proactive (generally).
