First thing to do is clean your meshes. Triangles and smoothing don’t go well together. You also have loads of faces inside your mesh, this will only cause smoothing problems. Also remove your many doubles
When you have a much better mesh you can set smooth shading, add a subsurf modifier followed by an edge-split modifier.

i wish i knew what all that meant!
how do i get rid of triangles on a cylinder!
where are the extra faces?
thoy i had revoved the doubles!
how dop i do an edge-split modifier.
