To, start I am new to programming and am beginner level. My question's are as such:

1.Do programmers memorize entire namespaces or does a programmer reach a point in which they can look up a class in the MSDN library and understand how to use it to it's fullest potential?
2.What is the best advice an expert programmer can give to the beginner?
3.If you could change one thing on your way to becoming an expert what would it be?
4.Once one programming language is learned, is it easy to learn another?
5.What is the job outlook like and what is a typical salary?

Feel free to answer any and all questions.
