The black spots you refer to are probably carbon spots.  These are often removed by laser drilling a diamond.  A diamond examined by GIA will have a clear note of any treatments done to the stone.

The inclusion "chart" is usually found at the bottom of a GIA grading report and will show where all of the noted inclusions are.  The image of the same will be accompanied by a key explaining what each of the inclusions shown is.

There is usually an image of the diamond on the GIA certificate that shows where any inclusions are, whether they are visible to the naked eye or not. Depending on the clarity grade you should be able to tell whether or not the inclusions are visible (SI2 or above should be eye clean). As for any treated diamonds, the certificate should not any treatment done if applicable.

You would need to be careful at SI2 clarity.  Some stones will be eye-clean, others certainly will not.  Also, one other often overlooked fact is that people tend to forget that even stones with eye-visible inclusions can look almost flawless if the inclusions are put in the "right" place when the stone is set.

GIA reports will state whether a diamond has been treated or not.

If you can see Black Spots in a Diamond with your naked eye (unaided), it usually means only one thing: That Diamond is an I Clarity Diamond.
