Lawn Question, overseeding and other things.?

Hi, I just got a soil test on my lawn from the local agricultural lab. The recommend some more lime, as well as fertilizer levels of 20-3-12 in April and June, and 10-6-4 in late august, which is different from the fertilizer I was using. The question is, if I was planning on overseeding (I waited until these results got back so I have not done it yet, and we live in Boston area), what should I do from a timing perspective? Should I apply some lime, and use the 10-6-4 at the same time as a top dressing and starter fertilizer and grass seed. Should I do the lime and 10-6-4 before the seeds?, if so how long do I have to wait? The first frost will be here in about 3 weeks. Or should I get the seed down and germinating (using top dressing and starter fertilzer right away before the frost comes, and then put some lime and 10-6-4 right before the snow comes?

Thanks for any help!
