Yes. See FAQ 8.15 for reasons why and how to make it smaller.

Yes. You can't build your program without a compiler. (Unless it's written
entirely in assembly, or something...)

Advantages of protected mode? Basically:
- Direct access to large amounts of memory and swap space (up to 256M with
current CWSDPMI version)
- Bugs in your program cannot damage the system, and will be caught by the
hardware and you can find out. (NULL pointer derefences, etc.)

DPMI is an interface into protected mode from DOS. It's a fairly standard
interface and doesn't need a DOS extender, so DJGPP uses it.

I hope I answered your questions. If not, sorry, maybe explain them in more
detail.
