1) You overexposed.
2) You didn't perform a custom white balance that shifted away from the red enough when you shot.
A custom white balance will get you some colors other than red to work with. That's when the channel swapping will help you out. If you don't do the custom white balance right, you're essentially going to have an all-red photo. At that point, working in B&W may be your only choice.
You can also take a non-IR shot, and layer the two to get a different kind of false color effect.
I would say, go google up "Infrared post-processing" and see what other people are doing and how they achieve their effects. There are tons of different ways to mess with infrared.
Also, the
Flickr Digital Infrared group might have some good advice.
