Man we live in Canada, if your feeling to hot just open the window and go a bit faster.
Ripping out all of the A/C components would certainly save some weight and eat you would be able to put the power that would otherwise power the A/C to better use.
If your deadset that your going to drive the car into the ground and there will be no more owners of the car, then i say just rip it out. I guess if you had to sell it you could always put the a/c back in.
If i was in your situation I would probably take it all out with the exception of the dash controls (so it didnt look ghetto).
Watch out when you do this, many of the refridgerants and coolents in A/C systems are not good for your skin and some of them can give you frost bite (like aerosol cans) if handled incorrectly. Basically use gloves.
