It's better to have in on soon, than on late! 
You might want to remove your rad and give it a good cleaning. You'd be AMAZED at the crap that comes out, even when it looks clean.
Also - invest $50 in a shroud (TCP or whatever) that will help that crappy stock fan pull some more air through. The cooling design isnt' the greatest. A SPAL fan and TCP shroud will help a bunch. Also - install a switch to override the fan so it comes on whenever you want...
Also - install a temp gauge so you're SURE everything is kosher... i hate relying on idiot lights!
