Spybot-Search&Destroy 2.0 (coming soon, and still in testing) will include that feature. If Spybot prompts you that you need Administrator rights to do a specific task, you can always right-click the default Spybot desktop icon in Windows Vista and click "Run as Admin...".
Not at the moment, it is still in testing. However, v.1.6.1.41 is a RC for Spybot-SD 1.6.1. A beta for v.2.0 could be released probably next year or so.
