Don't be afraid of asking questions. stackoverflow.com can be you great companion when you first start. The guys there are really helpful. Regarding resources, I believe it depends on the kind of start up you are planing to work. Some basic algorithm design knowledge won't hurt. And I believe, the best advice might be not to get desperate when something doesn't work out. Just know that if everything works you are either not learning or superstar programmer. Meet each challenge with smile on your face, knowing that by the end of the day you're going to find the solution and learn one more thing. Good luck!
