Help with textures

[Starhawk]

Ok so I've designed some models in Wings and used the UVmapper.....however I cant figure out how the heck to texture the model from there?

I know you have to open the texture file in photoshop and edit it there but how do you get the texture BACK on the model you just made?

Also quick question for folks with photoshop CS2, how do you open one image and copy paste it inside another when using the texture feature?

I cant figure out how to get the freaking thing to import an image into a currently open image and I've honestly forgotten how to make a texture inside photoshop which sucks since I've lost the book

Any help would be nice.
