Blue onion is right really depends on how big your garden is. I have a medium to large garden and get plenty of stuff from greens to browns to put in them, plus i compost the neighbours grass clippings so I have 2 1mx1m wooden bins made from pallets. If you only have a small garden go with a dalek type bin they're light and when you do need to turn then they're easily refilled and emptied. You can compost kitchen waste (uncooked veg or fruit, peelings etc, no citrus though) grass clippings and woody stems from perennials, old newspaper, cardboard, anything natural really and it soon breaks down.
Yes you can put annual weeds in a composter leaves as well, but it depends how many you have, scale is everything when composting, you need to accommodate what create. You can build a seperate bin for leaves, and that's a different process and style of bin, but again it takes space.
There is a compost thread on here somewhere, hopefully someone will find it for you and put in a link.
