Shane, I came here too when I was first starting. Alot of nice people here to give opinions and tips. One tip is, don't go straight for it when you get it. You said your 16 no job and money is tight, so it may take a while for you to get the set. In the spare time, research how its done. Videos on youtube, here at the wiki section explains how to do it. It helped me alot when I was first starting because I was researching it probably 2 months (if not more) before I got the stuff, so I knew basically how to do it.
Also, try to shave as often as possible, maybe once every 2 days or so. That way you get practice and don't have to start all over again.
When shaving use both hands, don't try to use your dominant hand everywhere. What I do is WTG (going down your face) on the right side of my face I use my right hand and on the left side I use my left hand. Now when I do XTG (going up the face) I do opposite sides, for example when shaving the left side of my face I use my right hand and the right side using my left hand. Simply because (for me) its awkward moving your arm to where you can go XTG the arm on the same side of the face (if you can understand this)
Also, start by shaving your cheek and neck only, the chin and upper lip are probably the hardest parts to shave.
Hope you can get your razor soon and hope you do a good job your first time, any questions just ask!
