kd,
no problem. they have a pretty decent selection of AT (alpine touring) setups there. they rent boots as well, mostly scarpa lasers which will give you much better control over your skis than the koflachs. they are quite a bit heavier/beefier if you are just looking to tour the trails they'll probably be overkill. if you are simply looking to tour the trails, i'd look into a backcountry setup instead of AT. if you are looking to ski down trails or slides in the area, i'd go AT. let the folks at mountaineer know what activity you are looking to do, and they'll set you up accordingly.
as to 4 season tents, where are you going? if you are going to be in the high peaks, there are many lean-tos so you really don't need a tent, just a good sleeping bag rated about 10 degrees colder than forecasted low temps (to be on the safe side) and maybe a bivy sac for weather.
high peaks cyclery in LP and mountaineer in keene may rent 4 season tents.
