As far as I remember it would have been much more tricky to get rid of MX records if the A record information would have been purged before...
One step at a time. Once the obsolete A records are purged, it simply becomes a matter of running the named-checkzone program (which comes with the "bind" nameserver) and it flags unresolvable CNAME and MX records. I ran it a few months ago and cleaned out hundreds of bad CNAMEs and MXs; after the A records are tidied up I'll run it again. - Brian
