Not sure of any books, but some documents on the Gentoo Wiki about the
various projects are helpful.
I use /etc/portage/package.{use,accept_keywords}/* in a somewhat unusual
way. For each package
that needs tuning the USE flags beyond the eselected profile and some
globals in make.conf, I have
a file named "<catedory>.<pkg>" (e.g. media-libs.mesa) with a few handling
some multiples. This lets me
tune packages in a fine grained manner, and still see which ones I have
fixed quickly.
For example:
In eselect profile: default/linux/amd64/13.0/desktop/kde
In make.conf:
(may well repeat some from profile, try to group by functionality)
USE="smp \
cdr dvd dvdr css usb -bluetooth \
caps branding unicode ipv6 tcpd \
kde qt4 qt3support plasma gtk -gnome \

The last entry is an empty file to catch the "automagic" changes portage
may propose so that they can be
broken out into individual files. package.use/* is similar.
I have found some wedged cases where there isn't any way to solve it except
by using
some "unstable" arch packages (while waiting for them to be stabilized.)
It may seem unwieldy, but I fnid it much easier to deal with than one big
file with all the
packages isted in it.
For example, in /etc/portage/package.use/app-office.akonadi-server I have:
app-office/akonadi-server soprano -sqlite
which makes the emerge be quiet about having both mysql and sqlite enabled.
Don't be afraid to ask questions, it is an easy cure.
