One 5 lb. jug of Prodiamine 65 WDG will treat up to 5 acres depending on the rate used.
If you were spot treating on your St. Augustine with Atrazine as a post-emergent herbicide, then it should be fine to apply the Prodiamine anytime after that application. If, however, you were applying the Atrazine as a blanket application as a pre-emergent, then you would not need to use another pre-emergent right away.
In general, it is fine to mix a pre-emergent herbicide like Prodiamine 65 WDG and a post-emergent like Trimec as long as neither product label prohibits this mixture. Be sure you use the correct rates for each product. We also recommend a small jar test for compatability before mixing a larger tank. You also will need to activate the Prodiamine with irrigation or rainfall after at least 24 hours but within 14 days of the application, per the product label.

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. The Prodiamine will prevent your new seed from germinating.

On Bermudagrass you can use up to 2.3 lbs of Prodiamine 65 WDG per acre per year, which breaks down to 0.83 oz per 1000 sq ft. You can split up this amount into as many applications as needed. So if you are doing applications in Spring and in Fall, then your maximum rate at those times is 1.15 lbs/A (0.415 oz/1000 sq ft).
For Poa Annua (annual bluegrass) prevention: Applications in late summer or early fall before just before soil temperatures reach 70 degrees.
For Crabgrass prevention: Applications in late Winter/early Spring before soil temperatures reach 55 degrees to prevent crabgrass. In a warm place like Texas, you will probably want one application in late Feb or March and then a second application 6-8 weeks later. If you are doing this, then you would lower that Spring rate to 0.2 oz per 1000 sq ft.
