You don't need to buy anything too thick. 16 or 18 gauge should work fine, and not be too heavy.
For the size, use a tape measure to see how high up you need to go to keep the sheet between the mids, woofers, and TV. The tweeters aren't causing your problem, so you don't need to go that high up. (RPTVs have all of the magnetically sensitive stuff in the bottom anyway). The drivers are in the front of the speakers, and probably go back 3 to 4" tops. 1 foot wide on the sheet metal should be more than sufficient.
One other thought, you might be able to open up the TV and put the metal on the inside of the set. No fuss, no muss. If the TV is wood, use very small, very short wood screws to attach the metal. Use epoxy if it is plastic.
Good luck,
