Well, I have been having a lot of trouble with normals recently, so maybe I can help, or not.

A Normal basically just helps maya know how light will affect your object (I think!). So if you reverse your normals you have turned your object inside out. As gster suggested - try rendering your object before and after reversing your normals and you will see a big difference.

Sounds like you might not have reversed the normals properly. Try using the edit vertex normal tool- This will help you see what direction the normals are facing.

There are two different types of normal. Face normal and vertex normal. Face normals point in the direction of the face, and when flipped, the face is only visible from the other side (unless you have "backface culling" turned off - in which case it will still be visible from both sides).

Vertex normals specify how faces are shaded between.
