BLENDER 2.63 / 2.49B Texture Help

[Ecelon]

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 |
       

THE STORY SO FAR:
NOTE: Contains censored graphical nudity, which is censored, but still graphical nudity!
[spoiler]
  NOTE: I know it has Lightning - Valhalla Knight above, but as I haven't done a 360 preview of that model yet, I present thee with Lightning - Guardian Core Uniform
   
  NOTE: Be warned that this is a warning, warning you that you have been warned about a previous warning... I.E: CENSORED Graphical Nudity Time:
   
NOTE: A Chocobo, from Final Fantasy XII. I'd have done one from XIII but the alpha map is completely screwy!

Thanks in advance to those that help.
