Well I don't know the answers to all your questions but what I did is replaced all my lights with LEDs except for the high beams, fogs, and of course the headlights because they are LED already. And then I added some extra lighting. The fogs I replaced with standard yellow halogens for the yellow look (also with yellow vinyl over the housing), I replaced my high beams with philips crystal vision ultras (halogen) because I go driving at night up mountain roads a lot. They are WAY brighter than the stock bulbs. I installed LEDs for the brake lights, reverse lights, license plate lights, turn signals, side marker, and the side mirror turn signals, the map lights, dome light, and trunk. You have to heavily modify the side mirror light housing to install LEDs there. You may need to slightly modify the license plate light housing for the LED to fit. For my map lights i extended the light circuit down to the floor with speaker wire and used cheap ebay white LED strips so that the map lights also light up the floor area. My front turn signals have 2 colors, so when they're just on with the headlights, theyre white, but when turning, they flash off and amber. All turn signal LEDs require load resistors EXCEPT the side mirror ones. I dont know why. For the trunk I wasn't satisfied with a simple LED swap so I tapped into the circuit and added another cheap white LED strip in there. Very bright now. And I added another white LED strip in the glove box with a fuse tap and a magnetic switch. Hope I can help!
