Resizing

 I`m just new to icon-making and I`d like to know what`s the best way to crop pictures down to 100 x 100. 
Let`s say I have an image that`s 800 x 500. I crop the width down to about 503 so it`s almost a square already since it`s near 500. 
So I just go to Image > Image Size and change them the size to 100 x 100 but I`m sure there`s a better and easier way to do this.
I think it requires changing the Canvas size? Can someone please teach me how? I use Photoshop CS3.

Thanks in advance! :)
