The two vacuum lines need to be plugged, the emissions hardline can be removed from the engine bay, it runs to a small section of hose underneath the passenger side firewall before going into another hardline. Just make sure it's left open to vent, otherwise fuel vapor will pressurize in the line, causing blowoff when you open the gas cap. You can get more involved and remove the entire hardline from under the car all the way back to the tank, then leave the last piece of hose tucked away in the frame rail somewhere.

The carbon canister's purpose is to draw out fuel vapors from the tank during driving and reburn them in the engine to reduce the emissions. The drawback of course is you're burning it in the engine, leaving soot and residue in the intake manifold. The overall effects of taking it out are negligable, no worse than the output from the exhaust system.
