Don't anchor your pinky. Thats a very bad habit to develop. Your right hand shouldn't rest anywhere anyway, and it certainly shouldn't be anchored. I'm not just talking shit, I've played guitar for years and taught some too. I've had lessons from some of the best players in the United States.
If you don't believe me, just watch some concerts of guitarists you'd like to emulate and I bet you that none of them 'anchor' their pinky.
Your right hand should be above the bridge, unless you are doing palm muting in which case its acceptable to mute the strings with the side of your plam, but you don't want to 'rest' the hand anywhere. Thats a very bad habit. If you do it, it would be really worthwhile for your playing to make an effort over the next couple of days to break that habit.
