[assuming (1) means "represents java source file, rather than java class]
1a) node.getLookup().lookup(ProjectMember.class).getOriginal() -> 
FileObject, you can check for mimetype, extension, ...
+ check that the node is indeed a project member...

1b) node.getLookup().lookup(SourceCookie.Editor.class) != null

[assuming (1) means "node represents a java class"]
node.getLookup().lookup(ClassElement.class);

2) node.getLookup().lookup(SourceCookie.class).getSource() ?
