Have some questions about Acronis True Image Home 2011?

Hello. I have a few questions regarding Acronis True Image Home 2011.

I'll keep this simple.
 
First, I already have Acronis True Image 11 Home. I am running Windows 7 Professional. I know this older version of Acronis is not compatible with Windows 7. So I will get the latest version to date.

Question 1: If I have Acronis True Image 11 Home, can I buy an ‘upgrade’ version or do I need to buy the ‘full’ version?
Question 2: If I can use an upgrade version, do I need to have the full version of Acronis True Image 11 Home ALREADY ‘INSTALLED’?
Question 3: If I can use an upgrade version, how does it work during the installation process? No differences from the full version?
Question 4: What does the Add-on for Acronis True Image Home 2011, called the Acronis True Image Home 2011 Plus Pack do for me the normal version do?
Question 5: Is the Plus Pack really worth it for the extra $29.99?
Question 6: Okay, I ask this: Do YOU recommend ANY OTHER YOURSELF YOU like?


Please answer my questions.  

Thank you!
