Don't let the drywall discourage you. The key to an easy drywall job is to trowell the finish on as smoothly as possible, maybe even going over some places again with the trowell to knock down any ridges. Then, to smooth the joints, use a damp sponge instead of sandpaper; it disolves the ridges and allows that compound to fill in any holes left. Besides, it makes it easier to breathe.
Another little trick is to lightly spray the ridges and scrape them off with the 6" knife. My son taught me those little tricks and I've used them and recommended them ever since.
