Unless you've got some fairly specialized equipment, your best bet is to take it to someone and let them do it. You'll need to evacuate the refrigerant as well as pull a vacuum before putting any refrigerant into it after you've replaced the lines. I watched a Youtube video where someone replaced his own compressor but had to purchase about $350 worth of tools just to make it happen. The vacuum was around $200 and the valves/gauges were around $80 I believe. There were some other things he had to purchase as well.
