That's an awfully high nitrogen content lawn fertilizer for this time of year -- unless you will be sprinting across yourlawn with the spreader! This handout from K-State Extension, excellent informatrion you can take to the bank. Oh, and IMO, buy cheap. My turfgrass professor always told us to buy the cheapest fertilizer we could find, because they are all equal in quality in the eyes of the plant.

And here is an excellent article on weed control, including crabgrass control.

These principles and schedules are tailored for Kansas lawns, but apply to most of the central part of the country, and except for the timing of some products, you can apply them to cool season grasses (fescue, bluegrass, ryegrass) in most parts of the country.
Ideally, you should apply the preemergent and the fertilizer separately, and bear in mind, crabgrass doesn't germinate until the soil warms and the temperatures are consistently in the 50s. If your weather forecast is calling for cold temps for awhile, you might want to wait on the crabgrass control product.
