 You don't need a the whole chroot thing if you only want flash and java
working in your firefox.
In this case:
* use firefox-bin (a 32bit firefox binary provided by portage)
* the (usual) 32 bit flash plugin
* a _32 bit_ libjavaplugin_oji.so : the java plugin file, you could copy
one from your other gentoo 32 bit system. I don't know if this is just
luck, but I only have dev-java/blackdown-jdk-1.4.2.02 which is compiled
in 64 bit and it does work!

mplayerplug-in does not want to work for now as far as I have tested
(that is, not so much).

Hope that helps.
 I think building and maintaining a whole 32bit chroot is really
annoying, and after all you can run most 32bits apps out of a chroot
with the provided emul packages.
