I am no expert but I think it really depends on what you want to use your yard for. Do you want to grow veggies at any point, have kids or a dog? If so, your top soil should probably be scraped off because of who-knows-what can be in it like flecks of years gone by lead paint.
Not worried about growing edibles? I was suggested to roto till the entire backyard and put in sod. You can rent one from home depot for a day. I don't know the price of sod but usually it's reasonable compared to the pain of growing from seed. I've done patches and it's such a pain.
I'm a novice, so someone probably has other advice.
Perfect time to get started and good luck!
