The first thing to do is to check your State University's "agronomy guide" for the seeding suggestions. Climates vary considerably and the seeding suggestions for seed type, rate, and ground prep will change accordingly. For example: in Ohio we're outside of the suggested seeding dates for permanent grass seedings right now, but if you're in western Washington and have influence from the coast your seeding periods will be different. Likewise, the intended use makes a difference, in Ohio we'll seed pasture areas with fescues at a rate of less than 20 lb per acre, if it is a turf seeding the suggested rate may be 300 lb per acre or more.
The roller will probably not push rocks down as well as you'd like, you'll have a "lump" wherever there is a rock.
I'm guessing from your region that "burning" it off with fire is probably a no-no. Consider a chemical burn-down instead. Mow it good now, let the trash break down over the winter and then have it sprayed when about 4-5 inches in the spring.
Either way, see what is appropriate for your region, Washington and Oregon are grass seed country where much of the grass seed we use in the US is grown, I'm sure your local University Extension or Soil and Water Conservation office can get you on the right track.
