I rinse the biomedia in a pail of tank water I've taken out before I start to clean. Most carbon packs say to replace it monthly, some, like the internal Fluvals, say more frequently. It should tell you on the box the carbon came in.
What kind of filter do you have? For me, the length of time between cleanings depends in part on the filter being used.
