For fertilizer and lime, a soil test will teach you far more than anyone can on here. Throw and grow type mixes need good soil contact, not covered up necessarily, but good contact. Spray the area a month ahead of seeding to kill all the weeds and give you a fighting chance. FWIW, I'm not a fan of most of the store mixes. You can do better with 40lbs of cereal rye mixed with 5lbs of clover/acre.
