+1 on Brad Gillis on his Night Ranger stuff. Yeah, some of his stuff is over the top but very useful to learn if you want to use the bar more.
Also, for health reasons, when I'm playing enough to be stage ready, I have to ration licks that tire my left hand muscles. Because of that, I learned to use the bar for effective vibrato, especially on >12 fret stuff. I worked up a cool vibrato by using my right hand little finger looped under the bar with a very loose grip. Meaning my hand moves much more than the little finger. I've gotten compliments from some of my friends that hate whammy bars so it must be ok.
BTW, in this clip I'm using a Mesa Mark III that I built in a 1967 Fender Bassman chassis in '86.
