To add to what Brian said, if you feel like you just don't know a lot about what you need to do, one of the easier and more enjoyable reads is a book, "A Random Walk Down Wall Street". It has been updated many times, but the core story is just a very understandable discussion of how to think about long-term investment and matching it to your needs was well as how the market works and some of the vocabulary that is sometimes a barrier.
