I think FPSC automatically changes .tga to .dds so no worries there.
I think Keith uses Gamespace.He might drop in to give you a few pointers.I have never used it so I don't know anything about it.
There are a wide variety of converters out there...I even found a mega converter somewhere.
If I can figure out where it is and/or how I found it I will post a link or something.
I use Ultimate Unwrap 3D to convert most of my files to .x although I am sure there are others.
