Lawn renovation: Too late in the fall?

I'm in the Northern Virginia area. I've recently moved to a new home and the previous owner didn't care much about the lawn. The entire lawn is filed with crabgrass (about 95% weeds). Its a .25 acre lot. I've been told its better to just kill all the weeds with roundup and start from scratch.

I've sprayed roundup for the entire lawn about 2 days back. I'm planing to stick to the following plan:

1) Dethatch the entire lawn after all the weeds are dead
2) Spread about 10 yards of compost and some top soil
3) Aerate the lawn
4) Spread fertilizer & lime
5) Overseed the lawn

Since I've sprayed roundup 2 days back, how long should I have to wait before I get started on the over seeding?
I've been told its better to wait about 4-6 weeks before I do the seeding.
I'll be using tall fescue. Will 2nd or 3rd week of October will be too late to do the seeding? I would like to wait as much as possible after spraying round up...at the same time don't want to get too close to winter.

You input is appreciated.
