Get as many VHS films as you can.

A record player and some records. Seriously my dad has a huge collection of records. Maybe some type of rotary phone or a neon phone. Something that looks like wood paneling. Or some 80s style curtains.

I seriously need to see if I can find a way to make a rug out of those or something.

Checkout vkimo's Retro Rooms for inspiration!

I would also add hanging model airplanes into the mix 

Vintage shirts for the closet.

One thing I do, I print out 8x10 color photos (on photo paper) of things like old advertising and promo pics from tv shows.  I buy the "frameless" frames from wal-mart for $3 and hang those pics all around my room.  You can also get 8x10 frames from Dollar Tree...and they kinda look retro because of how cheap they are.
