What you are talking about there is reindexing the system tables.
But "recreating the indexes" as a solution to file growth and
performance problems is not this. Instead, what you do is drop the
index and recreate it. At least, that's what I have gathered from
the "reindex" scripts that were sent to the -general list a little
while ago.

Yes. As someone else suggested, it sounds like you need a full-time
DBA, at least for a little while.
