One paper that might answer some of your questions is

On the (im)possibility of warp bubbles
Authors: Chris Van Den Broeck
Comments: 5 pages, 2 figures; intended as a Comment for Class. Quantum Grav
Report-no: KUL-TF-99/22
I discuss the objections raised by several authors against Alcubierre's warp drive geometry. I argue that all of these objections may, in principle, be overcome, although important practical difficulties remain.

Nobody really knows how to make exotic matter, it is just something that is possible in the equations. The closest thing is quantum effects like the Casimir effect.
