The chrome is easy. Go over all of it with fine bronze wool (mark that - bronze wool, not steel or brass), and around the chainstay bridge, you might want to use some oxalic acid to help you along (though I dare say some persistent bronze-wool work would remove the rust just the same - just with more effort.

Careful around the seatstay caps at the top (where it says "RALEIGH") - easy to flake the chrome off when burnishing it around that area.

As for the paint, run some KIT Scratch Out or Meguiars Scratch X on it, and it'll come out like new. The "Campagnolo" sticker on the top tube and down tube are not original - take a hair dryer to it to loosen the glue if it isn't already (and use Goo Gone to wipe out the sticky residue), but be careful not to loosen the Raleigh decals next to it.

P.S.: Yours is an '85 - components and yellow decal highlights give it away. The '84 had a slightly different component mix, and the following decals w/red-white-blue highlights (note that the component group on this machine is not original):
