Glad it was helpful, John.

That doesn't sound right - there must have been something else causing that.
$epc is a perfectly valid variable name: the $ character is treated exactly
like a letter in JavaScript variable names. It's a common (and recommended)
convention in jQuery code to use a leading $ on a variable name that
contains a reference to a jQuery object, as in this code:
var $epc = $('#edit-profile-country');
If you still have a test page showing the error, I'd be curious to see it
(either a link or the page source).

$(fn) is simply a shorthand for $(document).ready(fn). They do exactly the
same thing.
