U-Tube will have many video's of milling instructions and just people simply using there mills. There are even school based vids you can view.
One thing is for sure, metal working and wood working are totally different. All though you will find the same intuitive instinct that helps you with woodworking will also help with metal. The feel of a machine when its working can tell us a lot. Feeds and speeds are much more important with metal, and its much easier to kill cutters/bits when doing it wrong.
Here are a couple links I do have though.

I have a set of vids somewhere I cant find that are very good basic learing vids for milling and lathe. They are on U-Tube, but when I find them I will come back and give a link.
I may have already linked to these but here are the vids I was looking for.

I hope this takes you to ten vidoe's. If so watch them all they are pretty good. At this same site you can find many video's if you spend time looking.
