In addition to what SavingRaven said, you'll need to go to Tools > Material Database > Tilesets > Import and then import the tileset to get any sort of transparency whatsoever
That's not true. I've never imported any of my stuff through the Material Database...ever. All my stuff has transparency/translucency where I want it to be. If you have a graphics editing software that can export your bmps/jpegs/pngs with transparencies (such as Adobe Fireworks), you'll be just fine.
