Important question: Do you know where your bindings are mounted right now?
If you don't know, here's how you can find out. Your ski boot should have a little arrow or a line on or near the bottom, indicating the center of the boot. When you click your boot into the binding, you can check that line against the marking chart on the ski (which probably reads something like "center, -1, -2, -3" etc) to see where your bindings are actually mounted.
This thread is pretty helpful for identifying where your skis are mounted:

Here's the deal. If you're just starting to learn how to ride switch, it's not that big a deal if you're not center-mounted. I learned how to ride switch on a pair of Atomic carving skis (non twin-tip of course) mounted somewhere way back on the ass of the ski. Center mount is "cool" these days, and it really does help with high-performance switch skiing, but if you're just learning, it's not necessary!
The real problem here is that remounting will affect the longevity and performance of your skis. To mount bindings you gotta drill holes in your skis, and let's just put it this way: you don't want to drill any more holes in your skis than absolutely necessary. Also, remounting bindings close to where they were mounted before can really be problematic- your skis will snap easier, your bindings might rip out, etc.
Here's what I say. First, find out where you're mounted. If you're within 4 centimeters of true center, I'd say stick with them the way they are. It won't make a big difference learning to ski switch. Trash the hell out of those babies, and then center-mount your next pair.
