I second the above, be careful but also enjoy "learning by doing". This is a pretty good small boat, and the best sailors (seems to me) learned on small boats.
This is actually a small overnighter, so a portable VHF radio (say around $150) would be a good investment. So would a good anchor, chain, and rode. Those two will get you out of many potential scrapes.
Work on your upwind sailing. If you can get good at that, then reaching and running will be a walk in the park...
Have fun, keep learning, and keep asking questions.
