I recently bought these:
https://www.sparkfun.com/products/10535
RF Link Transmitter - 315MHz
https://www.sparkfun.com/products/10533
RF Link Receiver - 4800bps (315MHz)

All I want to do is:
Light up an LED on another breadboard.
On one side I have Arduino>RF Transmitter.....RF Receiver< LED

Is this possible?
Just send a digital high to the input of the transmitter and connect the output of the receiver to an LED and it will work?

I doubt the output will source or sink enough current to light a LED.
Also, expect interference from neighbours remotes, doorbells, garage door openers...

I imagine an Arduino is somewhere in the mix too, right? You need to download the Virtualwire library.

You need at a minimum 2 arduinos, one transmitting and 1 receiving using virtualwire, or you can use some specialised hardware designed for doing this.
A pair of SC2262 / SC2272 encoder decoder chips will do all the hard work.
