Evan,

Since you have VSEnterprise, you should already have Backoffice 4.5, right? That gets you most of your list.

You might also consider, if allocation of budget to other "goodies" is a consideration, the DirectAccess Action Pack, available thru distribution channels to resellers:

It includes for development only:

Products
The latest editions of these Microsoft products, including relevant service packs, are included.

Windows® 98 Second Edition
Windows NT® Workstation 4.0
Office 2000 Professional + Microsoft Press Office 2000 Resource Kit
BackOffice® Small Business Server 4.5 + Microsoft Press SBS Resource Kit
BackOffice Server 4.5 + Microsoft Press BackOffice Resource Kit

You can also add the Office 2000 HotKit with Office Premium for $99:

That might leave you a few more $ for other things.
