The NetBeans projects in the jdk/ repository were written by a different 
person who has since left Sun.  As far as I know, no-one is looking 
after those projects at this point.  I cannot speak to their contents.

Yes, that would seem best.

This morning, we identified and fixed an issue with the setting of 
javac.bootclasspath in the langtools/make/build.xml file.   A fix has 
been pushed to the TL/ family of repositories. This should fix being 
able to build langtools with JDK 6, so no additional changes to 
javac.source and javac.target should be necessary.

Noted.  I mostly work on copies of the langtools repository so setting 
values there works OK for me.  I accept this may not work for everyone.

This would only work if you are using NetBeans all the time.

There should not need to be any NetBeans project specific hints, because 
you can configure and use make/build.xml and make/build.properties with 
Ant directly, without using NetBeans.

Please bear in mind that some of this issues you have been fighting have 
been caused by a mistake in make/build.xml, for which I apologise.   For 
the most part, you should just have to set boot.java.home to build 
langtools, and target.java.home and jtreg.home if you want to run the tests.
