Also, for transparency you can select the selection you want transparent with the wand tool (4th button on the top row) then invert your selection. With the selection inverted hit ctrl+c and then ctrl+shift+v to paste in a new window. so...
If there is anything you'd specifically want, I'd be able to help with those.. I don't know what would be useful to you and what wouldn't!
Oh, that's 'my' 'fuzzy-selector' (lol).. 'Wand' might actually be a more commonly known name for it, though, so I'll make sure to add it, so there wont be any confusion.. - Thanks for bringing it to my awareness!
* By the way, that picture-illustration of yours is fab, so I was wondering if I may add it?.. *
