How to record?

I have recently come into contact with a recording programme known as cool edit pro 2.1. This programme allows me to plug the computer into a mixing desk, which then allows me to record sound either direct or through microphones. For the music on my music video i will be recording it myself using a recording programme and a mixing desk. The quality of the sound will depend upon many things. For example; the echo in the room you are recording in, might echo onto the recording. In addition i will need to take alot of time into getting the recordings to a good quality.
