As far as my understanding goes, USE flags allow you to specify the
support you want when you compile stuff. For example, if you want xmms,
mplayer, noatun etc. to support ogg vorbis, you need to set the
oggvorbis USE flag. For sake of completeness, I added everything I
though I would ever need, which makes for a lot of USE flags. However,
my system compiles cleanly, apart from the odd blooper such as
kdemultimedia not compiling unless I use the ~x86 masked version of
speex.

You get more features supported but the trade off is larger binaries and
slower performance.

I don't use optimisation more than -O2 as this can cause problems during
compile. In addition, use of distcc and ccache cause problems for some
compilations. I've just done an emerge -u world and it took 18 hours to
compile, but it's worth it as it was generally very trouble-free.

Not AFAIK.

You do not need /home mounted during the install, but I'd make sure it
was mounted before I added any users other than root.
