It should work.  You need to adapt the file myproject.jos, of course.
Especially the load and preserve section must match your package
names.  The load parameter tells which packages and classes the
obfuscator should include in the obfuscated code (if needed), and the
preserve parameter gives the starting point, usually the main function
of the code.   Everything that is preserved is not renamed at all.
Note that you need to preserve the methods, it is not enough to just
preserve a class.

Yes, as long as you do not use reflection or native code, it should
work.  If you use reflection, you must be careful to preserve all
classes, methods and fields that can be accessed via reflection.

No, its main function is to rename all identifiers to short and
unreadable names.  Normally the code is still decompilable and the
decompiled code can be edited and compiled again.  All strings are in
still in plain text in the class files. However, it is much harder to
read for a human as all class names and function names are obfuscated.
