Rio has said much of what I would have said but anyway, it sounds like a nice setup for DH oriented touring. You could lighten it or make it heavier (bigger) depending on how you intend to use it. Boots and bindings could suit a bigger ski but as an all round ski the K2s look good for various conditions. Don't get too hung up on kit – a good skier can ski the downs well on almost anything and a fit one with good technique will make it up the climbs faster than an average one with superlight everything.
I like Maestrales, and they are very popular. I can only compare with NTN and older AT/ alpine boots and don't have fussy feet so can't offer much beyond everything that Rio says above. And I was pretty determined not to like them. Pretty light, but several lighter options that are also cheaper. And stiffer, heavier boots that are cheaper too.
You could go for a lighter dynafit binding if you wanted – advantages/ disadvantages of the various models documented and discussed pretty well on various forums. I would go for the cheaper and lighter version personally – the stuff some people do on them makes it seem that the more expensive ones are just for show, or silly big skis.
Whilst I'm converted to a tech setup, like globalti I do reckon fritschis are still very good for either dipping your toe in the water or if you are after one ski for everything. Rumours are they are bringing out a tech binding with some interesting features soon that may be worth waiting for. Depends on your priorities I suppose.
I'd be interested in hearing more reviews of the waybacks ( the K2 backups maybe worth considering also). Dimensions appear reasonable for all round use, look quite versatile, some good deals around on them.
Skins wise, I'd go for Black Diamond – they seem to last well, attachments are pretty reliable and straightforward in tricky conditions.
