If you're showing information that might be personal, I won't recommend using a cookie, but using a server-side log-in mechanism.

Also, if the list is too long (a cookie may only hold 4kb of data), you should be using a unique id, easily generated in PHP or in JavaScript, and save all the data on the server, then when the user's cookie is presented to the server, it'll pull out the relevant data.
