Under your scheme, it would actually make more sense to not delete from the cache until after the updates to the DB have been completed.
Uhm, that's what I'm doing. After the transaction is committed, I do the cache delete and then the redirect.
Anyways, let's say that's a matter of taste. I personally think it will be a great help to cache. How precisely it is done is probably not important. Good luck =)
