You can install Xcode 4.2 and the iOS5 SDK in a different directory to your existing installtion, when installing choose to install in a different path (for example Developer-new). This way you can keep Xcode 3, but you will still not be able to develop iOS5 apps in it.

(even if it is possible, it is unsupported so you may run into problems later, whether it's technical or Apple just not liking it)

If you're not switching to Xcode 4 because of the new layout, then you really need to, future versions of Xcode will be [highly likely] be based on this, and you will get left behind if you don't make the switch.

No, The Xcode and IOS is always in same DMG file. You cannot upgrade IOS without upgrading XCode. Whether you use XCode 4 with previous versions of IOS.
