How can i add a specular and diffuse map to an object

Hello Everyone, I’m having real problems with getting my diffuse and specular maps into blender(2.49). Ive been soldiering away at this project myself and have hit a wall. Ive read everything google has suggested and still i cant for the life of me get the things to actually apply to my model. So if someone would be so kind as to explain it to me in simple english
I’d be very grateful, Thankyou.

RTFM
