Some good tips. I learned early on that sticking to a script doesn't work for me though. If I memorize it too well and then make even a 1-word error -> I think "oh crap..." and get more nervous -> more mistakes -> positive-feedback loop repeats.
Now I just make sure I remember the points in all the bullets (and the hidden bullets in notes) well. Many presentations (with the notable exception of conferences) are interactive too -i.e. the audience asks questions even before you get to "Questions?"- so you may not be able to stick to a script anyway.
Here's another way to give a really good presentation, but with lots of movement/action happening on the screen: http://vimeo.com/1925542?pg=embed&sec=1925542&hd=1
