BLENDER 2.63 / 2.49B Texture Help

I've currently been ripping the models from Final Fantasy XIII & Final Fantasy XIII-2. I'm currently unsure on how to use a certain type of map and was hoping somebody knows how to use them in Blender 2.63 or 2.49B or know a decent tutorial that I could peruse to my own delight! LOL
The maps are RGB and look like this...

Final Fantasy XIII
| Vanille - Nude_Body || Vanille - Nude_Hair

Final Fantasy XIII-2
| Lightning - Valhalla Knight_Body || Lightning - Valhalla Knight_Head |

  CHARACTER_Lightning_Valhalla_Knight_Game_U_Head_M.png (Size: 72.24 KB / Downloads: 1)

THE STORY SO FAR:
NOTE: Contains censored graphical nudity, which is censored, but still graphical nudity!

Thanks in advance to those that help.
