Advice from 'Hackers' and others says to copy,rename,delete rather than pack (safer) - and index rather than reindex (to control file bloat). Comments?

Can someone point me to FAQ or code sample that specifically handles a copy,rename,delete of a table within a database that has multiple tags?

I want to be sure I understand the nuances of renaming and moving tables around when they are members of a dbc.

Also looking for code example that replaces/automates index so that it functions like a reindex in a dbc table with mutiple tags.

My table will frequently change reccount from 1k to 100k, so recycling deleted records doesn't seem to be the best way to go.
