Interestingly, you had warnings for files "already" in existence, yet those files are specific to the mod in question. Obvious issue: Vista or Win7.
Your mods are being installed to places you are not aware of, thus they are not working properly. Check your Local/Application Data folder to see if you have undeleted files relating to swkotor. Make sure that your swkotor folder and all sub-folders have been unticked from "Read-Only".
That might be a start.... let us know how it goes!
EDIT: I see now that you have got the mod working, by installing the TSLPatcher on your PC. Odd that this is what it took, but I guess that results are all that matters.
Still, you may want to check into "ghost" folders, as you did have the warnings on files that should not have existed.

Reason: Saw that Riothamus had solved his problem another way
