Your Answer for Question 1:
You could add a small field (like a bit) that marks code as executable. This is like the NX field in the X86 processors that are just coming out. This would add to the complexity of the processor as well as require the operating system to check this field.

Your Answer for Question 2:
A number that is machine readable but less accurate in computation that a normalized number.  The results of computations on them can have large error margins.

Your Answer for Question 3:
To simulate a guard bit, this reduced rounding since x did not have to be aligned with the different exponent 1.

Your Answer for Question 4:
Going against the standard would probably be for performance reasons. For it ensures compatability/portability with other hardware platforms.
