Here is a cube...just for an easy example...Im going to be smoothing just the selected faces here because i want the bottom to retain its hard edges, and they dont need to be smoothed : )
this is the side view just so you can see how it is shading the bottom polys...
Now, when i Smooth the top i get discoloration in the bottom part of the mesh...this is really something i want to avoid...i want it to smooth the top without messing up the rest of the model
im not even sure if the normals are the problem because they look fine to me
if anyone knows why this is happening please let me know so that i can fix it : ) thanks

You need to use cuts and extrudes to keep the bottom faces hard whilst smoothing the top.

First I set the custom polygon display to show hard and soft edges (display/custom polygon display....). This makes the hard edges show up as solid lines and the soft edges show up as dotted lines.
1. I created a cube like you had in the example using the settings shown in the pic below. As you can see the edges of the cube are all hard but the ones crossing through the middle of each full face are soft.
2. With the whole cube selected I made all the normals hard (edit polygons/normals/soften/harden.....). This made every edge hard.
3. I then marquee selected the top faces and selected the default smooth options (twice). As you can see, the top was nice and smooth but the bottom 1/2 of the cube has had the edges softened as well when they started off hard. This has also caused the darkening of the cube as you showed in your example.
4. I then marquee selected the edges of the bottom 1/2 of the cube and hardened the edges again. This got rid of the darkening and made the edges of the bottom 1/2 all nice and crisp again.
The little render at the bottom should show what has happened as well.
Hope this helps you...........
