I got a boost learning the guitar after I got a tascam guitar trainer CD-GT1. It has a built-in tuner, a bunch of effects, you can play along your CDs, you can loop a particular part, slow it down, change its pitch. It works great for me.

There is a lot of play-along books with CDs on the market that you can take advantage of later, but to get you started the right way is GUITAR FOR DUMMIES (I am not making fun of you, I have and love this book myself). A cd goes with this book, they may be available in a public library near you.

Don't give up, PRACTICE and you will have fun!
