Glad to have you buddy! You should go to the introduction page and tell everybody about yourself, not a lot of people outside of the gear nuts really check this part of the forum out.
My advice is post daily and post often on the forum. With guitars I suggest practicing 10 minutes a day every day for the first week and gradually increase your time from there depending on the soreness of your finger tips. Remember its better to play every day for 10 minutes then it is to play for a half hour and miss a day of practice due to your finger hurting.
As far as suggestions on what to play, I'm teaching my 5 year old son and my 6 year old daughter Chromatic scale right now. All that is is the notes played in order. So if you have an low E string you would pick the open string, then fret the first fret which is F, then the next one to F#, and then next one to G, and the next note to G#. This should be done with all four of your fingers and the notes should be picked clearly. After that string move to the next string which is A and do the same to it and the remaining strings. All Chromatic is is the descending notes on a scale. The same 12 notes always descend the same way. The scale is C, C#, D, D#, E, F, F#, G, G#, A, A#, B, C. When you repeat a note you've reached a whole octave. So depending on what string your on or what note your on you know what's above you and below you on the fret board. Very long I'm sorry good luck and welcome to the forum!
