On step 3 you don't want to do an UPDATE over your messages table, unless you have low traffic levels. Under high load traffic the updates will have a high cost, probably generating locks on your DB tables and slowing things up.
It's better to insert them on a separate table. If you don't have high traffic then it's probably not an issue.
