timing belt change

so i just hit 50,000 miles on mine 04 aveo and i remeber reading a very good how to with pictures on changing a timing belt a couple weeks ago and now i can't find it anymore. if anyone knows or has a good how to with pics it would be a great help if you could post the link, (as long as its ok with the admins), to where its at. also i was wondering what brand of timing belt should i get. and what is that tool that hold the cams in place when you take the belt off called?

Links to relevant info are great. Links for other reasons are usually spam.
