First, start with:

www.linuxfromscratch.org

As for understanding the early boot process, this is probably a bit dated by 
now, but it's what I learned from:

http://www.tldp.org/HOWTO/Bootdisk-HOWTO/

I'm told it's been replaced by this, now that floppies are passe:

http://www.faqs.org/docs/Linux-HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html

To understand the theory behind it all, the best resource is a touch out of 
date (2.4 kernel) but still good.  Chapter 1 (booting) for tigran Aivazian's 
"Linux Kernel Internals":

http://www.faqs.org/docs/kernel_2_4/lki.html

The big things that have changed since then are that the boot sector at the 
start went away (you now _have_ to use a bootloader like lilo or grub), and 
initramfs got spliced in as an alternative to initrd (and initrd will 
eventually be deprecated).

For PXE, this might have something useful:
