Okay let me see if I have this all correctly: I need seachem prime which removes chlorine, chloramine, and ammonia. Does that mean I still need a water conditioner?
Yes, Prime is a water conditioner. It detoxifies chlorine, chloramine, ammonia, nitrite and nitrate, plus heavy metals. Many of us recommend it for new setups, especially with no live plants, as it covers everything.
I need to do a 50% water change. I need to add quick start to the new water along with stress coat. But I don't need to add anymore bacteria supplement. (Were you saying that once the bottle is opened it's only good for one day after that?)
You should be doing a 50% [meaning half the tank water volume] water change daily until the tank is cycled. You can read about cycling in a "sticky" post at the head of this section of the forum, but here is the direct linnk:

As others suggested, use the products you have as directed on them. They can't hurt compared to ammonia and nitrite.
Once I get the testing kit I need to test the ammonia in my tap water and I need to invest into a master kit? Did I get it all?
This is a reliable kit, the API Master Combo which has pH, ammonia, nitrite and nitrate. And yes, test your tap water for ammonia, nitrite and nitrate just so you'll know if any of these are present; we can discuss what to do later if they are. Test the pH too, but put some tap water in a jar and shake it very vigorously for several minutes before testing [no need to do this to test aquarium water, just tap for pH]. This outgasses any CO2 which will cause a false pH reading.
