Purchase advice

I currently have Norton Internet Security & Ghost. Security is about to expire & the ver of Ghost I have is not compatible with Win 7. I'm looking at buying Norton 360, ver 5.0. 360 indicates backups but I'm not sure if it has the full capabilities of Ghost. If I purchase 360, does it replace both Internet Security AND Norton Ghost or do I still have to back up everything with Ghost.? Or is ther another option?
