An electric kettle is nice to have, but not essential. They boil water much faster than a stove top kettle, but the end result is essentially the same. Some of the higher end electric kettles even allow you to set temperature controls so that you can make sure your water is the perfect temperature for some of the more delicate teas like green teas that require water between 160 and 180 degrees.
You should go with whatever steeping device you think you would use most often. I find myself reaching for my over the cup infuser far more than my beautiful tea pots with strainers. It's a personal preference, but I find my infuser to be my go-to steeping device.
Tea should be stored away from air, light and moisture. I would avoid the freezer or refrigerator because they create moisture. A simple air-tight tin or tea caddie would work perfectly, preferably one that is not see through.
Green tea is heated to prevent it from oxidizing. That is what makes a green tea a green tea. It comes from the same plant as all other types of tea; however, it is never allowed to oxidize. The way it is heated plays an important role in determining the character and flavor of the tea. Traditionally, most Japanese teas are steam heated which gives them a very vegetal, grassy flavor. Chinese green teas are more often bake cured or pan fried, giving them a nuttier, more mellow flavor. If you favor the Japanese variety, I recommend Gyokuro or a high quality Sencha. For Chinese green teas, I love Dragonwell, Snow Dragon, Pi Lo Chun or Spring Jade. If you are looking for a flavored or scented tea I recommend our Blueberry Pomegranate, Florida Orange Blossom, Wild Plum or Raspberry Green. I hope that helps!
