David's comment re how to access the alpha channel that 3DS creates in Photoshop is right-on. Regarding the "conflicting use of alpha" message… that will always appear when you're using the same 32-bit file in two different materials, when one material is set to Decal/Both and the other material using that map is set to Tile. The renderer has to decide which optimal way to use the alpha channel, and since decal and tile each have different optimal requires for pre-multiplied alpha, it can only do it one way. Most of the time you'll still get a decent (albeit not perfect) result, but if you want to avoid it completely, you can copy the .tga to another filename to create a second version of it and use both of them… each with their own setting.
