If you're determined and do your research, you don't need either - just go
with the freebee SDK. If you need a project setup for you and don't want
to know what is under the hood... then I'd say go with VSTO. To get back
(closer to) your question, VS2008 might be enough for many, but it might not
include the canned projects for building an office add-in. For that, check
the product comparison that the prior individual posted a link to.
