It doesn't answer all of your questions directly, but a good starting point
is the HOWTO at:

Is the existing board a custom one, or does it have a name you could run past
us?  Most of the existing off-the-shelf boards are already well supported.

A couple of comments on stuff I know about:

Fitting a compressed kernel + root filesystem + application in 1MB might be a
bit of a challenge, but it should be doable provided your app isn't large.
If you don't need to write to flash from your application, you don't need a
driver for it.

What type of PHY are you using?  You may need some minor tweaks if it's not
already supported, but the PHY interface is pretty standard so it shouldn't be
hard.
