Answer 1

I've never used it myself, but it integrates well with many simple editors and IDEs. I installed it and ran it in Geany just now. Works fine, but you will probably have to read the documentation to make good use of it. Such is the world of linux 😉.
It has good documentation on sourceware.org/gdb. Hopefully someone here can help you figure out if its worth your time learning this specific tool, but from the looks of it I'd say its promising. It can do most any debugging task and seems to work with many developing environments (unless you use winduws 😃).
