I have never heard of a vehicle's computer shorting out because of a bad IAC valve. The part price for the IAC valve (Idle Air Control Valve) of your vehicle is around $300. Labor price shouldn't be more than $150. I suggest having a repair shop simply replace the IAC valve. Don't tell them that the dealer said it shorted the computer out or they will say the same thing to get you to pay THEM the money to fix it. If they too say that it has shorted the computer then the dealer diagnosis is probably correct. If this is the case then you will probably have to pay the $2,500 as the dealer is the only one who can reprogram the new computer to your vehicle with there high-tech equipment and such.
For the headlamp price. If it is just needing a bulb replaced, you shouldn't pay more than $75 for that including labor. If it is more difficult than that, such as wiring issues, then it will cost more.
Hope this helps.
