Hi James,
Bardufoss airport is closest, but probably more and cheaper flight options to Tromso.
Car pretty much essential - think there's a rent-a-wreck type option available in Tromso - should come with studded tyres fitted which are also needed.
Lodge is the obvious base and recomended.
Personally managed without skis/snowshoes, but I was there during a low-snow year... so probably a good idea.
Climbing is incredible - gradually more info on specific lines etc. but still very adventurous. Conditions can be pretty variable, but likely stuff worth doing and if it's really thin should be better ice inland. The rock is pretty compact so stuff can be quite bold, decent rack including range of pegs useful for the mixed lines.
Worth taking hill food with you as chocolate bars etc very pricy out there... can be worth the cost of an extra 'sports' bag if a group of you.
As mentioned above - Rich Cross has been out there regularly so worth contacting - drop me an email through forums if any other questions.
cheers
Viv
