My situation is not the same as smoke's. IIUC, he (she? no offense intended either way) is wiring a 16x10 *attached* shop. I would just wire the circuits from the house box as alittle1 said. 6 duplex outlets on GFCI breakers, a lighting circuit and maybe a 220V circuit if needed. Local codes will rule, naturally.
Mine is essentially a barn and has to conform to different rules.
