Chris,,if it's nice and level I would rake/scarify, tine it (fork in all over the lawn to aerate) and reseed bare patches. Keep it well watered until germination.
Regular mowing, a good feed in spring plus weed and moss treatment. Don't let it dry out in summer. A couple of nitrogen feeds in summer too.
I top dress too but think if you do the above your lawn will begin to look good
