the red is your main power wire, it makes the stereo turn on. The yellow is the memory and needs to be hooked to a constant or always hot lead, so you don't have to readjust your stereo every time you turn it on and off.
The beeping sound should stop by itself. If the beeping does not stop, then your stereo has a technical issue. Once you get your stereo fixed, it should stop beeping after a little bit.
take it back to the guy who put the stereo in and complain.
To turn off the Pioneer DEH-1000, simply press and hold the "SRC" (source) button until the unit powers down. If the radio is connected to a vehicle's ignition, it may also turn off automatically when the ignition is switched off. Make sure to check the user manual for any specific instructions or features related to your model.
If I remember, turn the stereo on, enter the code using the 6 preset buttons. After the beep, turn the stereo off. Then turn the stereo on and it should be OK. I just pulled my radio to get into the dash.

The headlights turn off because you have accidently hooked the stereo's power wire onto the headlight relay wire. When you turn on the stereo, there's not enough power left to run the headlight relay. Thus, no headlights. Re-wire the stereo.
If it is an after market stereo, sound as if someone spliced the stereo power source wire (Hot Wire) into the wire going to the headlight switch.
the ACC wire from the stereo is connected to constant power (+12V)
