This article should explain anything relating to FTL travel. For the warp drive specifically, a bubble around the ship is created - most likely through a device built by the Omni. This bubble warps space around it, contracting it in front of it and expanding it behind, thus propelling the ship through space.

It's kind of like the idea you have here, though I don't believe it's explained what this "bubble" is made of.
