In a week I am going to Spitsbergen. I shall meet challenges with condensation in relation to going in from outside with temperatures from -10 to -20 Celcius, battery in these temperatures and exposure in landscapes consisting of mainly snow and ice.
Can you give me good advice on how to deal with these challenges? I have a Canon 5D with a 24-105 mm L IS USM.

Don't worry, I was there last week with a 20D and a collegue used the same setup you are bringing (5D and 24-105).
On a one day snowmobile trip to Barentsburg i kept the camera in a backpack exposed to the cold the whole day and never had to change the battery (tok about 100 + images), but i kept a spare battery in a warm pocket just in case. The camera wil get a layer of ice on the back and lcd whewn you breathe, but I never had a problem going in and out all the time the other days, just let it warm a bit when going inside before taking of the lens cap to avoid condensation.
If you want to be careful, put the camera in a plastic bag when going inside, as a cold camere will get some condensation, but going outside will not give you any problems.
Exposure: expose to the rigth, with images with mainly snow and ice I often ended up with a +2 exposere compensation.
Enjoy your trip, there are many photo opportunities there.
