Ideally you will want to do a selective herbicide along with a granular feed, if you feed the grass when you are treating the lawn the lawn will thicken up for the most part and grow in to the gaps that the weeds leave.
You have loads of options, selective herbicide on it's own, or you could mix it with some Sulphate of ammonia for a very cheap weed and feed.
Relay is recommended to be applied with Headland Xtend Soluble 46+0+0 more of a tonic than a feed but would still provide a nice green up.
There are plenty of weed and feed products on the market such as Everris Sportsmaster Cleanrun Pro that will do both jobs for you but not work as well IMO as the two separately
Past that your looking at a standard release 4-6 week fertiliser such as Amvista No. 3. Spring & Summer Fertiliser 20kg
The majority of the lawn care companies use 'controlled' release fertilisers such as Endure 20-0-12 where you can expect 10-12 weeks lifespan.
over seed after you kill them?
Any bare patch smaller than a grapefruit size should fill in by itself within a couple of weeks at this time of year. Larger than that then a scratch with a spring tine rake and a teaspoon of seed should do the trick on any normal garden lawn.
There should be dormant grass under the dandelions, etc, which once you mow off the treated broadleaf weeds should revive with the light.
