While moving around is normal in many guitar playing situations, you sound like a true beginner in need of some basics (a teacher would really help too):
1) Chord basics - There are several "folk" chords you should learn up in the 1st position. What I mean by this is, you can get chords A - G by staying up hear the nut (the top of the neck or the part of the fretboard furthest from your body when you are playing). I'd say that E, A, G and D are good to learn first, but you really should just commit to learning all of these major folk chords. There are TONS of places on the web to learn:

2) Scale basics - You may as well try to learn the Major, Minor and Blues pentatonic scales as early as possible. These scales, once mastered, will help you to understand how and why you can go up and down the neck like you want to. These basic scales also open the door for your understanding of the remaining scales. These scales help you to learn how to solo.
3) Basic Music Theory - There are mathematical (don't be scared) principles governing the relationships between the notes available to you on the fret board. These principles say why certain notes go together and why chords can be formed. Don't let anyone freak you out over learning this, it'll come as you learn chords and scales - they all go hand-in-hand.
Some more tips:
Technique:
While there are some ways to use your hand and fingers that are better in the long run, don't freak out or let others freak you out about "proper" technique in the beginning. The important thing as a beginner is to remain interested in and excited about guitar playing. There is so much to learn that you can easily get frustrated and chuck it.
I never took playing or learning seriously and thus, I've been "playing" for 20+ years and only know things from picking them up slowly. If I had of really disciplined myself, I could have learned a lot in a short period. HOWEVER, any hard-core Nazi approaches would have likely turned me off and I may have dropped it altogether.
Your Ears:
Further to my previous points, allow your ears to become familiar with the guitar (this is why staying in tune is important re: your previous thread). As you learn and explore the possibilities of the guitar, don't underestimate the value of "playing by ear." There is only so far you can ultimately go with "playing by ear," but it'll keep you motivated in the beginning and make you WANT to make music with the guitar.
I'm no expert (maybe the real gurus will show up soon), but this is what I've learned by being around guitars from childhood into my mid 30s today.
Good luck
