Tea needs no gadgets, unlike coffee where you need to have the water just below boiling, certain bar of pressure and grind the beans to certain size grind to extract it in 30 seconds...etc
Tea just like hot water and let it brew, the Chinese/Japanese have been drinking it for centuries without gadgets and its still best just put it in a pot and let it brew. You can be lazy and add milk if you like.
I have a set of tea cups and pot at home, will take a photo later, i got it in Hong Kong earlier this year.
I've only ever experienced one method of Chinese tea ceremony, wikied here for convenience: Gongfu tea ceremony - Wikipedia, the free encyclopedia. I've heard that the Japanese have their own elaborate ceremony as well. Not just as a decorative function, either. The people who do this can spend years perfecting the technique of making tea. Most important is, of course the tea leaves, but also the type of pot and temperature of water.
...And I should probably just answer the OP, right? *cough*
I use two types of pots, a standard Chinese porcelain pot like the type you find in Chinese restaurants, and a glass pot with a removable metal sift like Monolith's. The first one I bought cause it's cheap from Chinese stores. The second one was for the sake of a flowering tea ball I bought on impulse. The glass pot's not as great for keeping heat, but that's what tea cozies are for. Another thing about the glass pot, I worry that the metal sift gives off a metal taste in hot water. However, I've seen all-glass pots with glass sifts. Very cool, but not cheap. On a side note, I've been looking at purple clay pots, which you can buy from Chinese stores that specialize in tea. They're said to absorb the flavour of the tea leaf you use over time, and should only be used with one type of tea because of it.
I also have something like a plastic tea ball (I wish I could find a picture. It looks a bit like an onion bulb/melon baller that clamps around your tea.) I got it as a gift, but have also seen it sold in specialty kitchenware stores. I don't use it much, instead favouring my lo-fi way of tea leaves in a mug of hot water, and waiting til they all sink to the bottom. Good low-fuss for work.
As for buying tea leaves, you can search for places that specialize in selling tea and teaware. Or Chinese tea and medicine stores, which is where I get my stuff.
