I'm certainly not an expert, but it seems to me that the the continent with a lot of desert wouldn't have moutains with such huge ice caps bordering it. As a rule of thumb, and I'm sure that someone will correct me if I'm wrong, I would, from bottom to top go something like Ice Cap (a whitish color), Tundra (ie siberia in russia-a greyish color), some, and I can't think of the name of the climate zone, light greenish areas, along and near the equator you'll have your lush green areas as well as your biggest deserts..actually scratch what I just said...This wikipedia page, on tundras...lol has a chart on the right hand side of terrestrial biomes in the order, i assume, going from a polar cap towards the equator. Hope this helps ya man.
Though I wouldn't worry about getting every little zone in it's proper place, I would just be worried about not having say a tundra right next to a tropical forrest...in other words don't make jumps that far in planning the climate zones.
