Lots of good advice above. Also, since you are young, athletic, and just starting out, don't focus on the score, focus on good fundamentals and good swings. The results will come, but don't get worried about them now. The advice of irons-only above is good for this. If you know you won't reach the par-5 in two, or be able to cut that 250yd dogleg, you may just try to get the ball in the fairway with a relaxed swing. The scores will come.
