The first thing I would do is get everything off the floor and into a more comfortable working position. If you use a properly dressed hammer and learn good hammer control through practice you will see a huge difference in the surface of your work. The more you use a hammer the better you will become. Your hammer will become an extension of your hand, versus something held in your hand. Practice. Practice. Practice.
I like to keep 1/4, 3/8, and 1/2 both square and round on hand. I usually get 40 ft. of whatever size when getting it. I usually restock when I reach for a certain size and then say "I thought I had some of that".
