At present the ONLY things causing any sort of problem on 64bit are Flash and Googleearth. I have neither on my mythbox anyway.
The latest 64bit libflashplayer has an audio problem. The workaround is to use the 32 bit version with nspluginwrapper. 
I've had problems with Googleearth for years. I think it doesn't like me. Haven't actually tried it since I changed to 64 bit about 18 months ago, that is, back in the Cretaceous.
Whether it is a pure mythbox or not the only differences you will notice are good ones. 
But you MUST do a clean install. Save /home and /var/lib/mysql plus /etc for all the settings you haven't written down elsewhere and scrub the rest.
Note this is a good time to play with your partitioning, add a BIG video drive etc.
