Re-activation concern..?

I am very seriously thinking of doing a clean install of the Windows 7 to my computer on which I have installed Norton Internet Security 2012 (with over 900 days subscription left) and Norton Utilities 15.  I will be able to reinstall each of the softwares on my computer once Windows 7 has been installed.  I just want to verify in advance of that point that I will be able to re-activate each of the programs.  I don't see any problem since I will be re-activating the softwares on the exact computer, right down to the product model, board designator, and serial number. 

 

I haven't yet purchased the Windows 7.  I have to wait until I have the money to buy it.  Simply I won't be able to afford to re-purchase the Norton softwares once I buy the operating system. 

 

Please let me know in advance whether or not I should expect any reactivation snags.  I want NIS 2012 to be the first program I load and activate after I install Windows 7. 

 

Is there a technical support telephone number that I can call just in case I run into any problems?

 

I really do appreciate any help with my concern.

 

Thank you.
