Debian dual boot with Windows 7

[kramerjm-Re5JQEeQqe8AvxtiuMwx3w at public.gmane.org (James Kramer)]

I should be receiving a new computer soon.  It will have a copy of
Windows 7 installed on a single partition.  I have several questions:
1.  How difficult will it be for me to install a dual boot Debian
system on the computer?  I am familiar with Debian.  I just don't know
how difficult it is installing it with a new Windows 7 system given
Microsoft's proven track record of making it difficult for installing
dual boot systems.
2. I am planning to make a backup copy of the system using Clonezilla
so that in the unlikely event that something happens while trying to
install Debian, I can restore the original system.  Is Clonezilla the
best choice for this?
3.  It is my understanding that Window 7 comes with a built in disk
repartioner.  I was planning to use it to shrink the size of the
partition prior to installing Debian.  Is it better to use Gparted to
resize the Windows partition?

4.  Can I make an image of Windows 7 using Clonezilla and then
reinstall the image in a virtual environment?

4.  If it is too much trouble to install Debian as a dual boot,is
there something similar to Wubi for Debian that I can use?

Thanks in advance for the advice.
