I am just about to change a fuel rail and the injectors.
Is there anything I should be aware of or is it just a simple case of taking them off and putting the new ones in??

Just watch for fuel p**sing out.
Make sure you've cleaned up before cranking, and wait at least 10 mins inbetween fitting and cranking.
Also prime the system.

Remove the injectors/fuel rail
Block up the fuel line with toilet roll
Fit the new injectors/fuel rail
Clean up any spilled fuel and wait 10 mins.
Open the blue screw, turn the ignition on and as soon as fuel comes out of it, tighten it up.
Happy days.

I've completely drained the rail on mine and just started it as normal. No need to risk fuel squirting out of the schrader valve.
