Well to be honest the Storm Troopers are going to be pretty straight forward with little color variation. I'll prime/zenithal grey/white. Come back Paint all the black parts, eyes, helmet, joints, hands, weapon. After that highlight the raised parts of the armor and weapons. I'll do the bases separately assembly line fashion, by the time one base is dry then its time to come back for washes and then highlights. The rebels on the other hand will be the most time consuming as I'm leaning towards a mixed camouflage of various greens/browns, very much like the endor rebels and in general they just have more base colors to lay down and highlight.
