I don't think that mysql has clustered indexes, but I suspect it would 
be of minimal benefit in most cases.  The DB is not that large in most 
of the tables (except the program table).

Check out "mysqloptimize" and perhaps stick it in your cron?

For optimisation, the biggest difference I saw was from turning on the 
query cache.  Check the docs for details, I seem to remember that you 
just need to add a line like:
query_cache_size = 4000000
in your my.cnf file?
