Insulate cold side AC hoses? - Block heater core?

    It's HOT in the central valley of California. 104 today! A few heat related questions...

    I insulated the cold side AC lines on my xB a few years back with silvered bubble-wrap insulation covered with aluminum tape. Seems like a no-brainer, keep engine compartment heat away from cold hoses. I didn't do any before/after measurements. Has anyone here? Does it compromise the engineering of the AC system?

    Another trick I did on the xB was to clamp one heater core hose. The xB has mixing door flaps to control the heat, if the heater core wasn't heated it would mean less heat in the cabin. It cools down to 70 during the night from July through September, so the heat is not needed. Does this compromise the cooling system of the Tacoma? Or does the Tacoma use fluid valves to control the heat?
