Answer 1

Yes they are.

If you use jQuerys .html() it will take care of you. Looking into the jQuery source, this line is getting called:

jQuery.cleanData( this[i].getElementsByTagName("*") );

which effectively cleans up all data and events. This of course won't work if you're overwritting a DOMnodes innerHTML property explicitly.
