Using SMS 2 to upgrade to Office 2000 SR

I am running NT4 (SP 4 & 5) and Win95 network with SMS 2.0 (no SP).

Does anyone have the method to use SMS to:

1. Identify users with Office 2000 installed (not all will have the full installation, e.g. Outlook and Word only), i.e create a collection.

2. Create a .sms (.pdf?) file for the package.

Most of the Office installations were done prior to SMS installation, and include from CD and via network share. Will that make a difference with using SMS for the update?

I appreciate that I could do a network install using e-mailed shortcuts etc, but I am looking for the SMS method.

PS. I have used the Office Custom Installation Wizard to successfully create a package for the original Office 2000 version.
