Would this work on a jacket with "weather-resistant cotton-poly body" which doesn't have much resistant to water at all?

I believe this is made for synthetic fabrics, specifically for Goretex. If your jacket has a significant blend of cotton (>25-30%), I would suggest you try using a fabric wax (for example: Otter Wax). This WILL change the texture and look of your garment, however, it will add waterproofing and durability.

Must this be used by itself? Or can add it to detergent already loaded in the washing machine?

You would use this in place of the detergent. The bottle has instructions but it has a ratio of how much you need per jacket/ items you are waterproofing. Footprint USA is an authorized Amazon dealer for Grangers USA.

Do i always need to first wash it with "performance wash", then only if i need to re-treat the dwr, do i wash it again with the "clothing repel"?

No, if the garment is not dirty. If it is even slightly dirty, wash with Performance Wash then wash with Clothing Repel in two separate wash cycles.

Can I use this with a top load washer? What are the instructions for use with a top load washer?

I personally use a top load washer, and I put two cups in the top load washer. So far it has worked great for me.
