Michael--
@Justin Coopergave you some excellent advice. The only thing I would add to that is for you to jump into it! BP has plenty of information and resources. Make sure that you type in any topic that you would like to get information into the search field and you will discover that there will be several forums under each topic.
There is a book on this site that you can read, that will answer majority of the questions that you've asked. Take time to read as much as possible, but begin expressing your desire to get into real estate investing to your parents, family and/or friends. Go to REI meetings in your city/town which allow you to have networking opportunities and meet investors in your area. Do some volunteer work for a rehabber or investment company and learn as much as you can while doing so. You can even be an intern. DON'T WAIT!!! Mistakes will be made, as we all make them, but it will allow you to grow and learn more and more.
I hope things go well for you and please feel free to contact me with any additional questions.
