For that image, I'd suggest Indexed mode, with 8-bit alpha if it has a drop shadow. Don't confuse the BLPs Indexed format with the limitations of a gif, as it's palette is only limited by the number of colors, and not which colors. So if you have a red button, all 256 colors could be a shade of red ...and so on.
DXT is a lossy format - a great way of keeping colorful model and object textures small and looking good, but it's absolutely horrible at interface elements where every pixel counts.
Obviously No compression would also give you a great result - but it would be the equivalent of using a BMP, and the massive file size that goes with it.
As far as the viewer goes - as well as BLP2PNG, there's one format combination they don't support. Which is the main reason I made BLPNG in the first place.
The Corruption on the other hand, I'm not sure of the cause, and unless BLP Viewer has source code available, I'd have no way of knowing for sure.
