Not sure if this helps anybody or not, but I find the biggest problem with working with .tga in WoW comes when you're trying to get the alpha channel to work properly in Photoshop. Because it just doesn't.

There are several guides circulating on the web on how to get it to work, but I've found a simpler solution. Save it as .png. Open it in The Gimp. Save it as .tga from The Gimp. And the alpha channel works perfectly with WoW. Since I started using The Gimp for conversion purposes, I haven't had a single problem with the alpha channel in any .tga file whatsoever.

The format you should use for .tga in WoW - as already stated by others - is 32-bit color with RLE compression. The dimensions must be a power of 2. And somewhere in the back of my head a voice screams you should never use smaller sizes than 16x16. I have some faint memories of WoW client crashes after a patch that caused all textures sized 8x8 to completely bug out the graphics engine.
