I have three helmets. I only wear the third I bought cos I hate the first two. They are like boots – make sure they fit and you get on with them, same as a cycle helmet really. Then buy the goggles as some will fit that particular helmet better.
The basic amber lenses are fine for most conditions. The fancy mirrored etc lenses are more expensive and typically most suitable at the extremes such as very bright or very flat light. If I recall correctly, pink lenses are also ok for most conditions but with a slight lean to flatter light than amber(?). I tend to go with pink.
I only know about snowboard brands, which might matter to you, but Electric and Anon do have models that come with two lenses for similar money as those that have only one.
edit: I have two trips this year: Tinges, France and Jasna, Slovakia. Yay
