Yes, agreed. Taking Apple products apart for repair can be risky if you do not know what you are doing. Probably even more so these days with newer Apple products. If the scratches aren't too deep, you can easily buff them out and improve the look of your screen.
There are a bunch of junk polishing compounds out there that I have seen many people talk about online but this one worked wonders for me on both my iPod as well as my HTC Evo 4G screens. You might look into it...
