If you don't have a teapot and you want to brew without bags, you can actually just use a coffee plunger. (

Always try and pour over the leaves while the water is still boiling (doing this with coffee is not a good idea, it'll burn) and give the plunger a few pumps to infuse it a bit.
If using bags, one bag per cup will suffice, just take the bag out sooner if you want a weaker cup. Otherwise, two heaped dessert spoons in the pot/plunger and then one spoon per extra cup being made.
Momentarily dunking the tea bag in a spare cup of boiling water before your drinking cup will get rid of some of the caffeine if that's what you want.
Green tea and jasmine tea are quite nice (caffeine free too) and the Japanese even have a tea drinking ceremony. Earl Gray is a good breakfast tea.
Just learn how strong you like it, after that you can decide what type you like and whether to use bags or leaves.
Personally I don't like too much milk in my tea and never in the oriental teas. I don't use sugar either, but that's a matter of preference.
