Usually you would do this by calling on the
org.eclipse.wst.jsdt.ui.JSdocContentAccess class on a file in a
JavaScript project's Include Path. You can get a model for the entire
file using
org.eclipse.wst.jsdt.core.JavaScriptCore#createCompilationUn itFrom(IFile) and
then iterate through its children as you wish.

The closest thing we have for that kind of task is
org.eclipse.wst.jsdt.internal.core.util.CodeSnippetParsingUt il#parseCompilationUnit(char[],
Map, boolean), which is very much internal. You can, however, then use
a org.eclipse.wst.jsdt.core.ast.ASTVisitor to walk the AST for comments.
It's not nearly as easy to use, but then arbitrary standalone files
aren't a use case in which we're heavily vested.

Actually, many of the AST nodes your visitor will come across offer to return their JSDoc ranges; it's then up to you to either cast the IJSDoc object into something you can use, or read the documentation content from the buffer yourself. As for the issues with hover information, I'd need more reproducable steps--preferably in a bug report--to investigate. It's possible that the code responsible for converting your text selection into a resolvable element ran into trouble, as there may be some issues dealing with working copies in editors.
