We had a requirement to pass at a distance for locals hence we all bought civilian equipment and had an ecclectic assortment of skis, boots and bindings and because they were civilian they were better quality than issued stuff where quality is determined by the lowest bidder. As the folks have said, better to rent some stuff first to find out what fits your needs before you buy. You and I carry the same weight, however you seem to have been stretched beyond "normal" height and you will need a longer ski than most. If you are going to carry some additional weight and are looking at backcountry skiing my preference would be metal edged skis, higher than normal cross country ski boots, and a good touring type binding that you can repair on site if needed that matches your skill level.
