A few ideas/tips:

1.  BE ABSOLUTELY CERTAIN NOT TO CONNECT USING A 0.21 CLIENT ONCE YOU'VE
STARTED!!!!!!!!!  Disable all of them once you get started or you could
have one messy database (assuming you have the locale issues).  There
are ways to get around this, but they require care.

2.  You can just run mythtv-setup from any updated system to update the
database.  Be sure to examine the console output - the GUI just seems to
do nothing for a while when it applies update after update.

3.  If you want to do your headless server first, just export
DISPLAY=hostname:display to redirect the windows of mythtv-setup to
another system.  I'm pretty sure that mythtv on gentoo requires libX11/
etc even if it is built backend-only, but I'm not 100% sure on that.
Just run xhost +backendserverhostname on another PC running X11 to see
the console.

Just a few ideas...  At this point quite a few people have done the
upgrade on Gentoo, but the more complex the setup you have, the less you
can probably afford to be on the cutting edge.

The biggest issue I had personally was that the script mythtv uses for
the backups died silently partway, and I didn't realize this at first.
So, when I restored my database I was missing about 40 tables (just
about everything starting with "R" and on alphabetically).  Fortunately
I had made a manual backup of my own and was able to use this instead. 
I'd recommend just doing a plain old mysqldump on the database before
starting just in case.
