For your workstation, you really need a good chair, one that adjusts to have your feet flat on the floor while keeping your elbows above your wrists while typing, and if at all possible adjustable height rests for your arms. A 2nd-hand Aeron chair is definitely, definitely worth your money. Your wrists will thank you. Also, the top of your monitor should be at eye level (stack books or whatever underneath if you're too cheap/broke for a stand), otherwise you will hunch your shoulders over and get upper back pain. Listen to me, O Teenage Hackers, or one day when you are as ancient as I you will wish you had :-)
