Cydia is the app installer for the 2.0 software so if you are looking to install apps on your jailbroken iPhone then yes you need it.

Cydia also has infrastructural functions in the jailbreaked environment (similarly to the "BSDsubsystem" that previous jailbreaking used). So if you have a reason to have a jailbreaked phone, don't delete it. If you don't need your phone jailbreaked, then ... probably you're better off just using the official firmware than jailbreaking it for no reason and then deleting Cydia.
