Yes, Norton Ghost has this capability

I have used Norton Ghost for many years.  I have setup enterprise 
installations and many imaging solutions.  Norton will allow you to image 
dissimilar drives.  I have only used Norton Ghost to create an image from a 
drive and then reimage to a larger drive. I have never had success imaging to 
a smaller drive, for obvious reasons. I have used Norton Ghost to create 
images and then setup a PXE server so enterprise clients could choose which 
image they would like to use at boot time.  Along with roaming profiles (for 
windows side) and NFS mounted home directories (for linux side).  This 
created a fairly mobile and safe environment.

Norton has fairly good documentation in their knowledge base.  I have not used 
any forums besides experts-exchange when dealing with complex imaging issues.

Many use Knoppix or QTParted to accomplish resizing and manipulation of 
partitions.  There is an open source product called Partition Logic, 
http://partitionlogic.org.uk/ , that can accomplish some of the things Norton 
Ghost can do.

Not sure on this one

It should not change any of the above answers as all imaging products I have 
seen allow you to select a source and destination.  These can be USB, CD/DVD, 
disk drives, even flash memory (I have used ghost to image an embedded system 
using compact flash).

Hope this helped a bit.
