Well, not quite. Quantum teleportation works about thusly: Particles 1, 2, and 3 are at Point A. Particles 1 and 2 are entangled, and Particle 3 represents a qubit that is to be transported to Point B. Particle 2 is moved (not FTL) to Point B. An operation is performed on particles 1 and 3 such that their superposition is collapsed, classical information about Particles 1 and 3 is produced, and Particle 2 now has information about particle 3 in its quantum state. The classical information is sent (not FTL) to Point B and used to apply a transformation that converts the quantum state of Particle 2 into an exact replica of the original state of Particle 3, producing the qubit intact at Point B. Hence potentially useful for some applications, but not FTL travel or transmission of information.
Wormholes, on the other hand, would permit FTL travel according to certain solutions of the laws of physics as currently understood, even if they are completely impractical from an engineering point of view, and may not, in fact, exist.

Switching the locations would get you plasma that would quickly return to normal atoms, and switching the charges would get you antimatter. Both still have positive mass, and would therefore be useless for propping open a wormhole unless used as a scaffolding for something with negative mass. Antimatter has some interesting properties, but I don't know of any that would be particularly relevant.
