If I were you, I would take the bow straight to your nearest outfitter.
Have him adjust it for you (if possible) and look for some cheapy aluminum arrows. Easton XX75 aluminum arrows are pretty reasonable and you won't cry if one gets bent or lost. The outfitter should be able to tell you the correct spine weight needed, and field tips are what you want for practice.
Check this out if you don't mind making your own target... it will save you a ton and takes all of 15 minutes.
