Er, whoops, didn't read the rest of your e-mail and hit submit by accident.

To do what you want, I suggest querying them all and then storing them 
as an option in the database. When you fetch the option value (the 
data), it'll be pulled from the cache.

Check out one of my plugins for an example:


It does basically exactly the kinda thing you're doing. Without caching, 
it does ~300 queries. With the caching of the output to one option, it 
cuts it down to just 2 or 3 and then with WordPress' caching on, it cuts 
it down to just one I believe. :)
