The first thing you should do is take a soil sample and find out if and how much lime and fertilizer you will need. If you aren't seeding until spring add the pelletized lime now. If the area is flat, I would seed it. Mulch over it with straw or hydro mulch. I've hydroseeded over an inch of snow and frozen dirt and had 95% coverage in the spring. I would use a rye, blue and fescue mix. Starter fertilizer is just that, put it down with the seed!
