Desk Height

When you are sitting down the height of the desk should be about the height of your elbow when your feet are flat on the floor.
Since you can not normally adjust the desk it is best to adjust your seat height so your elbows reach the desk. In general the desk should be about 20 to 28 inches from the floor.

Ergonomic / how should you use a mouse

Ergonomic Mouse is to be selected to the fit the hand of the user who will be using it mostly.

Ergonomic Mouse wrist / palm rest makes the positioning of the hand over the keyboard comfortable. 

The size of the Ergonomic Mouse matters and hence while selecting you need to ensure that you have to apply only a minimum force to generate movement. Normally puck devices should be small in size for using with single hand with a width of 1.5 to 2.5 inches, length of 2.5 to 4.5 inches and a height of 1 to 1.5 inches.

How often should you move away from the computer?

Take short 1-2 minute stretch breaks every 20-30 minutes. After each hour of work, take a break or change tasks for at least 5-10 minutes. Always try to get away from your computer during lunch breaks.
