Hi, why Helical?1. I dont see why bearing pressure would be different for and MSE wall, but look into what Geogrid does for you. 2. My first thought would be to get with geotech firm and inquire about strenghening your load bearing soils with lime or cement. 1000 psf is really low. Try to find a mid point between a wide footing and strengthening existing soils. 3. Deep foundations may be necessesary, with caps and continuous footing. Look for an on center reasonable spacing for drilled shafts. What do you mean by traffic in calculating overturning moment?
