I wouldn't mix them if you don't have strong (legacy) reasons to do so.

Sure, do it the same as described in this mail, but instead use

     (html jQuery: #spinner) show

to fade in the spinner. Similarly you can setup to show the spinner
globally for all AJAX actions by adding the following expression to
the bottom of your page:

    html script: (html jQuery ajaxSetup
        onBeforeSend: (html jQuery: #spinner) show;
        onComplete: (html jQuery: #spinner) hide)

Search Google and the jQuery documentation for more samples.
