Tim, This really fills me with sadness. We're yet to get a date for migration, but I was really hopeful that it would be painless.
Whitelisting by IP is a mess. We have an open problem report on this, and it has been open for about 6 months. They once told us it was fixed, but it is not. Also, "X-Gm-Spam: 1" can happen for messages from whitelisted IP addresses. We attempted to use content filters based on SourceIP and add a custom header, but that does not always work, either. However, I have not investigated this second case in depth. Overall, with the exception of overally aggressive spam markup, we have not had too many problems migrating from an onsite appliance to GoogleApps. We use routing by group membership to send email to non-Google systems and that works well. There are a few tricks, though. Anyone interested, please ask away.

I was in a position to whitelist some security mailing lists, but thanks to google's taking white listing as more of a suggestion than a fact that was only partially successful. And depending on how a list is configured it may not be possible to white list it. I don't remember the details, but for example, the SANS lists could not be white listed and google required white listing each sender (and, as noted above, takes that more as a suggestion to deliver).
