Get a particular module's information programmatically Is there any function to retrieve all the hook used by a particular
module and also 
A function to return all menu links (along with its description) created by
    a particular module



  I looked into module_hook and module_implements but both
  were used to find whether a particular hook is used in a module. But
  what I need is vice versa.


I need it because configuration options for a particular module can be easily found by getting menu links in a page as a overview.
No - as you've already discovered, the association is the other way around (i.e. a list of modules against each hook, not a list of hooks against each module). Nothing in Drupal's core needs to know a list of all hooks a module implements, so no such function exists. As there's no requirement for a module to declare which hooks it provides (though they can through hook_hook_info()), such a function would be difficult or impossible to implement reliably.

If you can trust that all the modules you have installed are well documented, you could write something that looks in the comment block of each function for Implements hook_, and build a list yourself that way. Or you could compile a list of all the hooks you're interested in knowing about, run each of them through module_implements, and build your list.
Assuming by "menu link" you mean a path provided by a module that has the default menu type, and will subsequently appear in a menu automatically, something like this will do it for all modules:

$menu_items = array();
foreach (module_implements('menu') as $module) {
  $func = $module . '_menu';
  if (function_exists($func)) {
    foreach ($func() as $router_path =&gt; $item) {
      if ($item['type'] == MENU_NORMAL_ITEM) {
        $menu_items[$module][$router_path] = $item['title'];
      }
    }
  } 
}


That will probably need to be be tweaked for your requirements.
