I would caution using GET since you can run into odd problems with 
caching in IE.

But in any case you can use formSubmit to meet all your needs.
The options array lets you override any HTML_AJAX_Request option, 
http://wiki.bluga.net/HTML_AJAX/HTML_AJAX_Request?

I think a setup like this would let you use formSubmit to submit to a 
class method
var options = {
  callback: function(result) { /* custom callback */ },
  className: 'AjaxForm',
  methodName: 'myformhandler',
  requestUrl = 'ajaxserver.php'
}
HTML_AJAX.formSubmit('form','target',options);

You could also do

var values = HTML_AJAX.formEncode('form',true);
remove.myformhandler(values);

If one of these options works for you it would be great if you could 
document it on the wiki.
