there are many tuts here already for rendering. Try using the search option and search for rendering you should find what you need there. Also another usefull thing to do after you have your render cut out to removed the fringe from around the edges is to Create a new transparent layer underneath the render layer From the menu click Layer/Matting/Defringe... A little window will pop up, set the pixel width to 1 and click OK. Thats prolly explained in one of the many tutorials here also
