Adding Textures In Blender 2.66

I am very much a newbie to Blender, having just got it yesterday. I have also obtained some models from the video game “Sonic Generations” to use with blender. When I import them in, they appear with no textures, only vague colors on their clothes. Their fur, skin, and faces are transparent. They came with textures in a separate folder. How do I add textures?

It appears you want to use blender before you even know the very basics.
