Help shooting high school graduation

I'll be shooting my sons graduation in a couple of weeks. It's outdoors on the football field under lights. I'll be using my 10D and Sunpak 544 with both my 28-135 and 100-400. I recently bought the flash used and don't have an instruction manual for it. Anyone know where I can download one? I've Google'd it to death but no luck If anyone can offer any help it would be much appreciated. All advice and comments welcome.
Thanks my friends,

Here you go danny http://dukesmanuals.com/sunpak/
it's the least expensive one out there.
I thought I had a 544 manual but it is a Sunpak 3600 that I have...
