I would go to the local home depot or someplace that rents an aerator.
Be mindful, it's a lot of work using an aerator. Then seed over top
using a broadcast spreader. Also apply starter fertilizer.
Make sure you keep the seed wet, watering just about everyday. You
should see some excellent results in the spring.
Personally, I use nothing but Lesco Products, to include their seed
(Team Mates) It works well for me. I heard of their products from a
buddy of mine who is a landscaper. (www.lesco.com for a dealer near you)

I had problems with broad leaf until I went to Lesco same with their
Dimension Crabgrass Herbicide. They actually have a pre-emergent and a
post-emergent in their product so even if you miss the window for
applying it, it should still work.
Good luck

Doing the whole lawn all at once is more work than I want to get into. So
I mixup a wagon full of soil, peat moss, starter fertilizer and the seed I
like (Tall Fescue). Then we go around to the bad spots and scrape them with
a 4-pronged cultivator, sprinkle the mixture and tamp it down. Hopefully it
will rain. It seems to work well here in Eastern MA. I don't like wasting
money on herbacides especially since they only leave bare spots.
