Yes, works just fine.

AMD64 is an extension of i386 architecture, not a completely different
architecture. To put it short i386 + new features = AMD64. So if the OS
is a i386 32-bit one, it will simply not use the new features, but will
work just fine.
Also, QEMU emulates a 32-bit i386 system by default, even on AMD64.

Yes.

Yes. The same as on i386.

"qemu-launcher" will give you a user friendly GUI for configuring all
the options, and do other useful things, and "qemuctl" is a plug-in for
"qemu-launcher" that provides a GUI for controlling some run-time
options. Grab both.
If you will run "qemu-launcher" from the terminal, it will output the
command line needed to run the QEMU with the chosen options, so it is
also useful for learning.
If you have any questions or suggestions regarding "qemu-launcher", do
not hesitate to contact me on-list or privately. I like email. :)

Also on AMD64 system, you should check if your CPU supports hardware
virtualization (run "egrep '^flags.*(vmx|svm)' /proc/cpuinfo" and see if
anything shows up). If so, you could try using "kvm", which may be
faster than "kqemu".
