We have upgraded from 2.0 to 3.0.  I had Microsoft help us with the upgrade.  We now have all of our sites in the new 3.0 environment, but some of the customizations that were done by the previous admins and not documented are not working. Does anyone have a good, inexpensive resource that can help us with this? Specifically look and feel customizations and navigation customizations and especially Xslt file properties.

Thanks!
