The tires are:

255/40R-18 Yokohama iceGUARD iG52c XL
Last year I tried driving around my neighborhood with the stock tires and I couldn't make it up any kind of hill and was slipping and sliding everywhere. This year with the winter tires I drive at the same spots with no problem. If I really gun it the car with fish tail, but for the most part it handled the hills and snow/ice around my neighborhood really well.
I still haven't taken it on the highway or more than 30 mph and am just taking it really slow and easy. Any tips for highway driving if I run into ice/harsh conditions? I'd like to drive it through a curvy mountain road (Glenwood Canyons on i70) and if conditions get difficult can the car handle it?
Also, can the tires handle about 350 miles of summer highway driving back to where I have the summer tires?
Even with proper snow/ice tires you have to be careful, always be aware you are driving in marginal traction conditions.
Years ago -- more years than I care to count -- I was told in marginal traction conditions -- like rain or show/ice -- to adapt a one gear higher than usual behavior. (Obviously this was back when manuals were the norm. Owners of automatic equipped cars can just let the automatic decide which gear is "best" and be ok.)
This one gear higher than usual was to reduce the amount of torque available to keep the car from accelerating quite so briskly and to reduce the chance of wheel spin and possible loss of control.
Also, I slow down. While 65mph or higher is ok in good weather even 65mph may be too fast in bad weather even on real snow tires. (Driving through a section of heavy snow fall on I-40 between Albuquerque NM and Santa Rosa NM a few years ago in my Turbo (on summer tires no less) I got in behind -- but with plenty of room between my car and the rig ahead of my car -- a slow moving big rig (empty) and we cruised along at between 30mph to 40mph and made it through unscathed. A number of vehicles that passed us at much higher speeds ended up off the road.)
Slow down and give yourself and your car plenty of cushion.
For a "reminder" of how quickly things can go wrong when driving in the snow visit Liveleak (liveleak.com) and search out the auto wreck videos, compilations. A number of these occur on cold/snowy roads and you can quickly get an appreciation of how leaving yourself plenty of room can help you avoid an accident.
Oh I forgot to mention: One thing I did with my Boxster is I put some bags of sand in both trunks (80lbs in each trunk IIRC) to give the car some more weight to help the tires bite better. Also, just in case I picked up a nice suitably sized tow strap -- don't get one too short -- and with the necessary hardware (heavy duty lifting u-bolt) to connect this to the towing eye so someone could pull my car out of a snow bank/ditch should something happen. But I was very careful and never even had to use this setup.
