The first thing you need to know when using an herbicide such as Prodiamine 65 WDG is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. You will need to use 0.185-0.55 oz per 1,000 sq ft depending on your lawn type and length of desired control. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix 0.185-.055 oz of product with for each 1,000 sq ft area that needs to be treated. Please refer the Prodiamine label to be sure of how much you will use.

A concern with your question is that you mention you will be reseeding your lawn, in which case you cannot apply the Prodiamine (or most other pre-emergents) before you seed the lawn.

You could mix a post-emergent herbicide or different pre-emergent herbicide with Prodiamine 65 WDG as long as the use sites are compatible, you are not using the same active ingredient in multiple products, and you calibrate the products to be used together. Any time you are mixing products together for the first time, it is recommend to perform a small test mixture first to ensure compatability. Keep in mind that post-emergent control (killing existing weeds) will be most effective when the weeds (in this case, dandelion) are young and actively growing. Another option would be to use a different pre-emergent, such as Dimension 2EW, which also lists Dandelion on the label.
We would need to know more information about your situation in order to recommend a post-emergent product for dandelion, such as where you want to use it (turf, ornamentals, etc.) and how much area you have to cover.
Prodiamine 65 is a WDG (water dispersible granule) formulation which means it must be mixed in a tank sprayer of some sort and applied that way rather than through a hose end sprayer. Hose end sprayers also are not as accurate as tank sprayers and have no way to regulate at what point you have put out a certain amount of product to keep from under or over applying.

If you did not water it in after application, then no, you would not want to compost your clippings.
