Please help me tame my room.

Please help me tame my room. I have included a diagram. if you download the PDF 1 inch is 1 foot. I also have hardwood floors.

I know I have a bass problem around 50hz (its bloated) and the again at about 100 hertz. Above that I have some echoing.

Please feel free to edit the JPG and repost it. I am thinking some corner bass traps in the back and wall hangings. Please let me know what you think. I am thinking about DIY panels over store bought.
