www.adagio.com has a large version of their IngenuiTea tea pot that will brew a whole pitcher of tea, then dispense it into your pitcher of ice, filtering the leaves as it does. Bill and I have the small ones that brew a 16-oz. mug worth of tea, we love them.
Any good linen supply should have the cases for storing and packing china.
Crate and Barrel has the quilted china protectors. I love mine.
I second the Adagio reference! Love their teas.
I've seen this Bodum infuser at various Tealuxe locations.
How fancy are you looking for as far as tea infusers go? Wal-Mart has an iced-tea maker kind of like a coffee maker. Or, you could do what my old roommate did—just use a coffee maker. Put the tea bags in the thingie where the filters go, dump in the water, brew. Works like a charm.
