Do I need all of this Microsoft programs?

Yes.

A lot of the C++ and SQL Server you are looking at could be used by another application you are running. I would consider doing a little more research before just uninstalling them. Certain applications install Visual C++ versions and SQL Server on purpose because they use them. You uninstall what the applications use, they no longer work.

Worst case scenario? You lose everything in the applications that rely on those installed components because you have to reinstall or you have to do a system recovery (lose everything and start over from scratch)

For all you computer guys out there, I realize a recovery seems a bit of a stretch from uninstalling redistributable C++ packages but I said "WORST" case scenario.

Best case scenario? Nothing happens and you continue to use your computer as normal because those installed components are no longer needed.

If it were me, i'd look for other ways to clean up the computer or add another hard drive.

Not really, but keep Microsoft Office Enterprise 2007 - it probably costs about $200.

MS Office 2010 Word, Excel & PowerPoint use the same 'new' formats introduced in MS Office 2007.

No, none of it.

If you are actually USING MS-SQL Server, you might want to keep that one until you convert your database into a better DB scheme.

MSO (Office) is replaced with LibreOffice, so you do not need that.

MSVC (Visual C++ development) is replaced by whichever C++programming tool you have chosen for your programming, if any.

Even Microsoft is giving up on Silverlight.

Pretty much, unless you just need a paper weight.
