How do i make these parts of my model smoother and less discolored? So i am pulling final strings together to finish my project and i have these 2(used to be more, but i eliminated them whit knife tool or edge loop) unsmooth or discolored meshes. How do i get rid of them? I tried knife tool and edge loops and they dont seem to really work(that well)....
You should avoid triangle faces, especially where you need smooth curved surfaces. Use quads instead.  

I fixed your model's normals to make it renderable but it won't be perfect...

You can solve some shading issues changing the blue edges back to normal. The blue edges are marked as sharp, this means they won't be smoothed. Some of them have been marked by mistake so you'll have to check.
This is how to "unmark" them :

In edit mode
1- change your selection mode to edge
2- select your edges and use Ctrl+E to open Edge menu
3- click on clear sharp
