I have a pair of Sennheiser PC161 Binaural Headset with Microphone & XL Ear Caps. They are very comfortable, have good sound quality, and survived my two year old playing with them. Amazon has them on sale right now for $74.95. They are not USB, but you can fix that with this.
Keyboard : Microsoft Comfort Keyboard. Gaming Keyboard: Saitek PZ31A Pro Gamer Command
Mouse: Logitech G500

I love and would recommend them all.
