Sound reflection is the hardest...I have a minor master's degree in acoustics after setting up our shared rehearsal space: Cohere Bandwidth. Our use is for rock bands so the construction of our space is super specific and not at all helpful to what you need. However, these little guys come in fun colors and are super affordable. About $31 per 3'x4' worth of tiles. http://www.amazon.com/2x12x12-CHARCOAL-Acoustic-Soundproofing-Studio/dp/B00ATPD9T0/ref=sr_1_4?ie=UTF8&qid=1443557641&sr=8-4&keywords=acoustic+foam+panels
You'd be aiming for about 30% coverage total over all your walls/floors/ceilings. Giant area rugs are spectacular. Whatever you do--don't paint acoustic sound panels. You destroy their effectiveness. Re: the shedding that Alex experienced, you'll get that from "glass wool" or fiberglass panels and that stuff's not fun to clean up and it can make you itchy. I'd also check on a spray-on solution for your ceiling http://www.sonaspray.com/ this product would completely mitigate any sound reflection off your ceiling.
