Office 2000 came with 2 CDs (in the Premium version anyway), but AFAIK CD1 has everything you need for Word, Excel, Outlook & PowerPoint, at least, and that includes the proofing tools. A repair won't undo any of the updates/customizations that you've applied (unless they've broken something, which none of the updates does - except that SR1a had to fix some flaws in SR1). Until I recently stopped using it, I never had any problem with using the Office 2000 repair function (which is also available via Help|Detect & Repair).

You certainly won't lose SR1a as a result of a repair. In any event, why aren't you using SP3?
