Where are they stored?
Does the newest SDK overwrite base classes from previous SDKs? (Does NSString.h now reside in two different SDKs or will the newest one take precedence?
What about beta 1, beta 2, beta 3 SDK versions? Does installing the GM/official eliminate the beta version from my Mac?

I want to clean my hard drive and I have about 18 GB remaining on a 160 GB drive. I'd like to just start over and reinstall OSX, download a fresh SDK, but I still have apps that are targeted to 3.1.2 and I don't want to be forced to only support 4.0.

Can I remove old ones?

Sure.

Where are they stored?

/Developer/Platforms/iPhone*/Developer/SDKs/ usually.

Does the newest SDK overwrite base classes from previous SDKs? (Does NSString.h now reside in two different SDKs or will the newest one take precedence?

No, you're fine to delete them. Each SDK is self contained.

What about beta 1, beta 2, beta 3 SDK versions? Does installing the GM/official eliminate the beta version from my Mac?

Sometimes, you can choose to reinstall them though

Most importantly, Can I still target 3.0 if I install the 4.2 SDK? (I understand the difference between base SDK and target SDK)

Yes
