It's common just to say "up", which is "ue" "Ue e iki mashoo" ( Let's go up )
Floors are formally referred to by their level, so 1st floor ( it Kai ) second floor ( ni-Kai )
third floor ( san-gai )
Also a three level building would be referred to as "san-gai date" ( three floor build )
You can say either, depending on what you mean. Usually you are asking someone to perform a sequence of actions: first, to come upstairs, and second, to see something. The way to say this is "Come upstairs and see it." But if you are saying that the purpose of coming upstairs is in order to see something, in response perhaps to the question "Why should I come upstairs?" or "Where can I see it?" then "Come upstairs to see it" is correct.
