look at any alpine ski with a telemark binding. you could ad a 1/2 skin or do a wax.
a three buckle boot like the scarpa t2x is a great choice for a-100cm waist ski.
I would get a plastic shell with an intuition liner. it will be best for a long life, liner is replacable and it takes a while to soften a plastic shell vrs a leather boot.
almost all plastic shell boots come with the 75mm 3 pin hole for CC or light touring so you can go back and forth.
It will be most benificial to spend a few bucks and get a set up that is less than 5-8 years old.
you can get screaming deals on all k2 tele gear like the anti piste or the piste off. also the backstash.
volie makes light skis that tour great and ski well. look at a drifter.
the key to skiing soft pow is to stay in the first layer, reqiuring beter balance and transition of the ski. the wider the ski under foot combined with proper length will give you the float you need at medium speed for CC/tree skiing
what are your specs, hight weight etc
also, look at TGR or telemark tips to get more insight on skiing
anything 85-100cm under foot in the corect length will do the job, tip rocker will help with the float.
sorry for the ramble, post back and we can keep it going...
