I can assure you the two issues are unrelated.
The upright can in front of the driver side strut tower is the EVAP canister, it has three vacuum lines attached to it
The horizontal can under the cruise control solenoid is the vacuum reservoir for the solenoid diaphragm. It has two hoses attached to it.
The headlights are electric.
Edit....if by gooseneck you are referring to the thermostat housing, the small canister with vacuum lines near there is the EGR solenoid.....
