Microsoft Office 2003 was released in on the 19th of August 2003. There are many other Microsoft Offices. Microsoft XP was made before MS office 2003 and Office 2007 was made after.
Earlier it was not possible but now Microsoft has released a update to open 2007 files using office 2003. More on this at http://new-digital-world.blogspot.com/2008/03/office-2007-files-to-office-2003.html
The short answer is 'No'. There is no need to download compatibility pack for 2007 office system if you are running MS office 2007. Compatibility pack is required; if you want to run higher version MS office program on lower version MS Office program.For Example:Want to run MS Office 2007 program on MS Office 2003: Compatibility Pack is Required.Want to run MS Office 2003 Program on MS Office 2007: NO compatibility pack required.
Yes, Ms office 2003 is backward compatible with MS Office 2000. But if you are an advance user who programs in MS Office 2003. than there is certain part of code written in Ms office 2003 does not work in 2000. That's very minimal.
All above are known for MS Office tools like MS Word, MS Excel, MS PowerPoint, MS Outlook and many more.

You do not. It must be saved in compatibility mode for you to open it with office 2003.
Open the file in MS Office 2010 and save the file in compatibility mode.
The major difference is file format. MS office 2007 uses xml file format ie docx, xlsx, pptx, etc.
The first version of MS Office was released 22 years ago - on November 19th 1990 !
