I've gotten good at removing the plastic covers on the engine bay, did my brakes a couple months ago and just last weekend I flushed the brake fluid also.
By the way, the best tip I can share to remove the coil packs is to use the hole in part 2 of the coil (pic on second thread). After disconnecting the wire, part 2 sits straight up. Wiggle the coil sideways first to loosen it, than use your finger or the shaft of a screwdriver to lift the coil, careful not to break it.

My coils were really firmly seated in there so i laid a big screwdriver across the valve cover and then used another through the top of the coil to leverage it loose. Worked great.

Don't buy the plugs from the dealer stealer. I've gotten quotes as high as $39.00 per plug which is ridiculous. Buy online or most auto parts stores can get them for you on the same day if they don't have them in stock.

Glad the visual helped 
I bought a whole set of wire brushes at harbor freight for a couple bucks, the trick to get more bristles into the coil is to cut the tip of the wire brush, the very tip is twisted heavy gauge wire with no bristles.

Probably not necessary but I had the wire brush in hand and only took about 2 minutes to run it through all the coils. The contact looked "shinier" (less dull/corrosive powder) which probably means better contact.

My Ride: 2006 525i with nav and blue tooth , the wifes
and 1999 740il, my beast
I just did my spark plugs also at 85k miles. I have the N52 motor. I used NGK irridium plugs. The original plugs were labeled BMW on one side and NGK on the other and were also irridium plugs. (2006 525i, build date 7/2005)
I used a deep standard socket to remove the plugs...no problem. With the N54 engine you need a 12 point spark plug socket. Not sure when a thin walled socket is needed.
Always apply copper based anti seize compound on the threads. Torque to 18 ft-pounds (216 inch-pounds)
Car seemed to run smoother.....Getting better at removing all the plastic and rubber stuff to get at the engine.
