If you have to seed some bare spots, skip the pre emergent in those spots. Pre emergent should be applied when you see the forsythias bloom, that's a good indicator that soil Temps are ready.
As far a fertilizer, that's up to you. I would do 1 synthetic fertilizer (scotts or like) treatment after the lawn is awake in the spring then stick with organics in the summer. You being more north that me, you can probably get away with a 2nd synthetic fertilizer in early May. If you are having a dry spell and no irrigation, I'd skip it. Thats how I handle my lawn for the past decade.
For weeds, I would go with a spray. Get yourself a backpack sprayer and find a good 3 way herbicide with a surfactant. Wear long pants, mask and boots. Don't be stupid and spray with shorts and flip flops on a windy day. Weed and feed, while convenient, is not as good as a spray.
I always recommend getting a soil test from your state AG depth, this will let you know if you need lime for any other nutrients. They'll give recommendations as well.
Here's a picture of my lawn yesterday. 1 acre of tall fescue in NC. I do all my lawn maintenance.
