You can leave both of those things free-balling. If the charcoal canister valve (top nipple in pic) is not connected to vacuum, it won't allow the charcoal canister to vent (no big deal). If the charcoal canister vent (bottom nipple in picture) isn't connected to the intake, the fuel vapors trapped by the charcoal won't have anywhere to go except the atmosphere (no big deal again).
If I were you, I'd go one step further and just remove the charcoal canister all together. The hose that still connects to it right now is connected to the fuel tank. It is a vent, controlled by a check-valve. It lets pressure (fuel vapors) out of the fuel tank as fuel evaporates over time. That thing can also just vent to atmosphere. No biggy. Unless you're that concerned about the environment.
