Yes.
If by commercial you mean selling just the binaries to third parties, no.

No.
You have a number of compiler vendors offering tools.
However, if you want to use GNAT, and sell just binaries to third parties,
then likely yes.

Many differences.
FSF GNAT is based on a more recent GCC.
Chances are that AdaCore's GCC is based on GCC 3.4.6 in many cases,
and more intensely maintained.

Bug fixes, ASIS (yes, no, some), varying levels of support for the 
new Ada 2005 features, and more.

Don't know.

Not aware of one.
