If I ever come across a good deal on some '00R Brembo calipers, or Alcons, I'm picking them up. I want more than the Cobra brakes now.

When I do finally upgrade the front's it will be a 00R kit. Might as well go full blown if I am going to do it.

Spike even with your big ol' shot you don't have any problems with just upgraded pads, fluid, and lines? Because TBH the Cobra upgrade even used is not really in the budget right now and I don't feel I even need that yet. Ford designed the brakes on my car and I haven't done SHIT under the hood to warrant more stopping power.

Nope stops me just fine. If I road raced or autox my car I would of done a different setup. But my car as of now is a street/strip car so my setup is good for my use.

Look at it this way:

At 35k, my pads needed to be replaced, so I did the Cobra swap instead. At 80k, only half my pads are worn. For $400, you get better stopping power AND longer pad life. If money is a concern, look at the long term benefits.

I'm sure it says so in the Haynes manual I just ordered, but how much fluid will I need to fill the whole system once I flush it out?

I got a large bottle, around 2 quarts.
