Custom Droid Radio Mount

So I am the happy new owner of both a Moto Droid and a 2000 Jeep Wrangler. However these two products seem to show no love for the other, at the moment in order to both charge my phone and play music through the car speakers I am required to go through a very awkward series of steps and entangling wires that seem to be bent on strangling me. As an avid lover of customizing my own items I wondered "is there a way to make this simpler?" and realized: screw simplicity, I can make it WAY more awesome! And so my endeavor began.

The Droid media dock can be interfaced into a faceplate in which you drop the Droid on it then slide it to the left, plugging in the phone into both the audio and the power. To the left of this is a smaller panel with the LED readout of what station the tuner is set to for when the radio is set to AM/FM, along with a volume dial, seek buttons, and buttons that switch the input between Aux, Cd, AM, and FM. The issue is I am a programmer at heart and have very little experience in electronics, I wrote out the binary circuitry with little to no problem, my problem is that I don't trust my novice skill when it comes to the calculations for volts and amps being received at parts of a circuit.

I think this is a ridiculous project and is way more complicated than it should be, and that is why it is awesome and needs posted on Instructables! Once building really begins I will take lots of pictures and make a formal write up to put up! Thanks everyone for reading this rant/plead for help!

I'm confused about one part of your post. Have you already integrated a dock into your faceplate, or is that a plan you have for the future?
