The commands might seem more complicated than "apt-get dist-upgrade", but remember Gentoo gives you much greater flexibility (USE flags, kernel versions, backporting, etc, etc).
Let me just post a few commented output "dumps":

# emerge -uDNa world
Usually portage updates itself as the first package. This time it was different due to a block (auto-resolved), but to be even safer I decided to start with updating portage explicitly.
# emerge -1av portage

*** Portage will stop merging at this point and reload itself,
then resume the merge.

As you see the blocker was trivial, just had to update logrotate first.

Remember to run dispatch-conf as soon as portage tells you to do so.

This is where people frequently get frustrated. However, you can easily recognize the "error while loading shared libraries" pattern and run revdep-rebuild. A better solution (a.k.a preserved-libs) is in development.
# revdep-rebuild
This updated a few packages, so I ran it once more just to be sure (it didn't rebuild anything).

It's a good idea to rebuild X11 drivers after updating X, this is yet another "standard" thing that can frustrate people who don't know about it.

# emerge -1av $(eix --only-names -I xf86- -C x11-drivers)
Then a standard kernel update.
Then a standard kernel update.
# eselect kernel list
# eselect kernel set 7
# cd /usr/src/linux
# zcat /proc/config.gz > .config
# make oldconfig
# make -j3 && make modules_install install
# module-rebuild rebuild
Then a GCC update. Note updated GCC update guide, especially no need to rebuild entire world! Just libtool.
# gcc-config -l
[1] x86_64-pc-linux-gnu-4.4.5 *
[2] x86_64-pc-linux-gnu-4.5.3
# gcc-config 2
# env-update && source /etc/profile
# emerge --oneshot libtool
# revdep-rebuild --library '/usr/lib64/libltdl.so.3'
# rm '/usr/lib64/libltdl.so.3'
Finally, a cleanup:
# emerge --depclean --ask
# revdep-rebuild
Finally, a few tips for DVD playback (Dragon Player decided to stop working):
# emerge -av smplayer
Then there was some glitch with udev rules resulting in /dev/dvd symlink not being present. Probably because of some udev or kernel update, because I don't remember changing hardware in that box. Anyway, it's quite simple to regenerate and later adjust the rules.
# rm /etc/udev/rules.d/70-persistent-cd.rules
# /etc/init.d/udev restart
You may need to manually edit /etc/udev/rules.d/70-persistent-cd.rules and replace dvd1 with dvd:
SUBSYSTEM=="block", ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:06.0-scsi-1:0:0:0", SYMLINK+="dvd", ENV{GENERATED}="1"
And that was it! Hopefully this little report will help someone updating a Gentoo system.
