Your angles sound good for what your doing ...It's a matter of personal preference and comfort.
I tend to prefer very slightly ducked , or forward angles like Pawlo.. makes carving hard easier for me.
I also like the front foot to be no less than 18 deg.....again , something that works for me.YMMV
As far as setback goes, all of my boards have 25-30mm of set back designed in , and I don't change that.
I'm just not comfortable on a centered stance, I like the tail to be a bit shorter so I can really dig it in when I have to..but this is also just a personal preference.
