You can do the window control by customizing the `display-buffer-alist` variable. That's a suggestion if you haven't yet looked at it.

Personally, I use the shackle package which is an interface to customization of that variable. I mention this because I control where the man/woman buffers open using this package ( https://github.com/kaushalmodi/.emacs.d/blob/master/setup-files/setup-shackle.el )
