I was tightening the screw on the top of the Steerer to tighten the cap onto the stem... I tightened too much and I broke the clamps on the thing thats inside the steerer. Can someone please tell me if that part is needed. Is its function only to cap off the steerer?

You boogered your star fangled nut. It's purpose is to adjust the preload on your headset bearings.

I suspect that you thought your headset was loose and you decided to tighten it up via the top cap hex bolt. That's the right idea, but you have to loosen the bolts that clamp the stem onto the fork steer tube first. Since you didn't do that, the bolt pulled out of the star fangled nut. I'll bet the headset is still loose too. That's why you have to get it fixed.

What needs to be done now, (and I'd get a shop to do it for you) is to pound the old star fangled nut farther down the fork (or drill it out if you're picky) and install a new star fangled nut. Adjust your headset correctly, clamp down your stem and you'll be good to go.

Oh, and don't feel like you're the first guy to make this mistake. I have a friend who did the same thing on an $8,000 tandem.

The cap controls headset adjustment. I'm assuming your talking about the star nut inside the steerer. Any LBS should have a replacement and they are very reasonable.
