@Kristen Schlueter you are on the right track. Explore the "Learn" section (see menu at top of page), starting with the Free How-to Guides, especially the Ultimate Beginner's Guide to REI. Figure out what type of investing you are interested in (unless you already have your heart set on something). Then, and this is very important, write down your ultimate goal - where do you want to get in RE investing. Literally, write it down on a piece of paper and post it up on a fridge or somewhere visible. Then, write down a goal for this year. Recite them every day :-)
Like @Mike Huang said, Brandon's book is a great reference. You can find it here:

To say the guy is passionate about REI is to say nothing and he's been spreading the love on here for a while. :-)
While you are reading all this stuff, think about: how smart is your monthly budget? how much exactly are you worth? If you have a house, how much equity (market value - mortgage balance) do you have? Do you have parents or relatives who have houses paid off? Do you know people who have cash sitting idly in the bank? Do you have skills you can offer other investors? Getting your mind thinking in this direction will help you find sources of money down the road.
Lastly, either search on here or go to meetup.com and find a local REIA group. Almost every town has one and most of them are free. Sign up and go check out one of their meetings.
That should keep you occupied for a couple of weeks :-)
