Need Advice on Upgrading Parallels, Windows 7 and Quickbooks?

Hello, I have been running Parallels 9.0 for a little over a year so I can run Windows 7 and Quickbooks 2012. I am running this on an iMac running OS 10.8.5 Mountain Lion. This has been fine all this time (barring the constant "Windows is not genuine" pop ups because I used a previous version from the old Dell that had been running the Quickbooks.) This changed a couple of weeks ago as Quickbooks 2012 had an issue that basically is necessitating my finally upgrading. I am a longtime Mac user and not much of a PC or Windows user, so my knowledge on that is very limited.

I went ahead and bought a new Windows 7 disc so I can finally install a fresh version and stop the pop-ups. I don't know if this is a good time to also upgrade to the latest version of Parallels. I also need to buy and download the new Quickbooks 2015 as they are retiring 2012 and my accountants want us to switchover.

So I am here asking what exact order I should do this?
I do not really need to upgrade to Yosemite but will if necessary, would rather not if its going to add another layer of problems. Should I upgrade to Mavericks?
Should I first upgrade Parallels? or should I leave it at Parallels 9?
How do I "reinstall" Windows 7 if I am already running Windows 7?

I'm thinking I can just backup my files and then leave my Parallels 9 alone, and just treat this as if I were installing Windows 7, assuming that Windows will let you over-write an existing version - or will it say I am already running it?

I know I would do the Quickbooks update last.

Any advice on all this is greatly appreciated as I am afraid to do anything! LOL!!!

Thank you!

Thanks Maheesh for your response, but this is not what I was asking. I am not interested in Yosemite or having to upgrade to Parallels 10 if I don't have to.

I mainly need to know:

1. How to install a new OEM version of Windows 7 when I already have Windows 7 running. I need to get rid of these CONSTANT popups telling me I'm not running legitimate Windows 7. This isn't an upgrade, its installing Windows 7 when there is already Windows 7 running.

2. If I reinstall the new CD of Windows 7 will this over write all my Microsoft Office and Quickbooks software? If so, I assume I will have to reinstall all that, yes? If I don't have to do that, it would be wonderful as I would rather not lose all my settings etc.

3. I presume that once I do all this, I can just upgrade my Quickbooks to their new version like anyone normally would, so that's not an issue.

4. If I understood your reply, I do not have to have Parallels 10.

Any help you or anyone can give me on the above questions is greatly appreciated.

Thanks!
