I want to compare our cache settings to other schools if possible please. Just to give me an idea before I start experimenting.....
If you could let me know what yours are I would apprecaite it - and of course any related problems you have had with caching / not caching etc....
FYI - I have set ours to:

Cache Limit: 750 Meg

Expire images after: 240 Hours

Expire web pages after: 120 Hours

Expire others after: 240 Hours
