Adrian's talk in the links I posted yesterday covers many of the different
types of virtualisation, including how they work.

Really, the answers to your questions will depend heavily on the
virtualisation technology you installed. I think Kubuntu has Xen packaged,
along with UML and Qemu. Do any of those ring a bell?

If you have VT support on your CPU, then Xen is an option, but the version of
Xen in the current (K)Ubuntu releases isn't new enough. You'll have to wait
for the next release of (K)Ubuntu to run Windows alongside Linux using Xen.
(I'm also not 100% sure that Vista is supported yet.) Other "user space"
options like Virtualbox or Qemu are more likely to give you success in the
short term.
I don't know of any virtualisation software than can boot a Windows partition
that is also used to boot from directly. It may be possible if your hardware
is very close to that offered within the virtual environment, but I've never
seen this work. You will almost certainly need to create a dedicated Windows
installation for use within your virtualised environment. Additionally, using
USB periperhals with virtualisation software can be difficult, which might
cause problems with your scanner, printer and other hardware.
Out of interest what model are your printer and scanner? There are relatively
few printers that can't be made to work with Linux, and I've found that
support for quite a few scanners is disabled by default and can spring into
life with a couple of tweaks.
If you're able to make the next LUG meeting I'd be happy to talk through your
virtualisation options with you.
