The support for user-mode and TAP networking is orthogonal to the
emulated device. However if you only want a few ports it's quite easy to
use port forwarding, e.g:

  -netdev user,id=3Dunet,hostfwd=3Dtcp::2222-:22

which forwards 2222 to port 22 on the device. I have an alias in
.ssh/config for accessing my QEMU devices.

I'll defer to others for this but generally when I want proper bridged
networking for a VM I use virt-manager/libvirt to configure it because
it can be quite fiddly to do by hand.
