Flashing a custom build
Anil Gorthy
Jean-Baptiste Queru
Turn it off (pull the battery if necessary), and keep both volume-up
and volume-down pressed while booting (yes, it's possible). That'll
get you straight into fastboot mode, and from there you should be able
to flash a factory image, then a custom build.

negligible time to flash, in comparison, so I suggest you flash them
all.
The exact sequence doesn't matter, you can flash them in any order.
You can add "fastboot erase cache" for extra cleanliness.
Personally, when working on custom builds from source, I use "fastboot
flashall", or "fastboot -w flashall" when I want to wipe all data.

interesting to know if it responds to adb at that point, but that
can't be done on a retail build since adb is disabled by default (for
obvious security reasons).

emulator, it won't work on any real device (and especially not one
built on an ARM CPU).
You'll find all the detailed information on this page:
http://source.android.com/source/building-devices.html and that'll
show you which build config to use, how to get to the bootloader,
where to download the proprietary binaries
https://developers.google.com/android/nexus/drivers and everything
else you should need.

Indeed, there are no 4.0.2 binaries, because 4.0.3 was already
available (and preparing and testing the binaries takes a lot of
effort).

You can flash the system only. Don't have to flash everything.
Unless you make changes to stuff that might be kept in userdata.img, then you'll need to flash both images (or erase userdata)

partition. You can use "fastboot flash system" to just flash that one,
though the difference isn't large as the other 2 partitions take very
little time to flash.
It's possible to work at the file level via adb. I don't remember the
exact details as I don't routinely do it, but at a high level this
boils down to:
adb stop # this stops the Android runtime, but keeps the kernel
running along with the basic system, including adb
adb sync # this updates the files on the device that have been rebuilt
on your machine
adb start # this restarts the Android runtime
I'll let other people chime in on the best way to build a single file
in a way that matches what adb sync expects.
