/**
* Evaluates 'check' type values.
*
* @param	array		The result array. The processed value (if any!) is set 
in the 'value' key.
* @param	string		The value to set.
* @param	array		Field configuration from TCA
* @param	array		Additional parameters in a numeric array: 
$table,$id,$curValue,$status,$realPid,$recFID
* @return	array		Modified $res array
*/
function checkValue_check($res,$value,$tcaFieldConf,$PP)	{

list($table,$id,$curValue,$status,$realPid,$recFID) = $PP;

$itemC = count($tcaFieldConf['items']);
if (!$itemC)	{$itemC=1;}
$maxV = pow(2,$itemC);

if ($value<0)	{$value=0;}
if ($value>$maxV)	{$value=$maxV;}
$res['value'] = $value;

return $res;

}


In your case $maxV will be 2.


Your tx_myExt_itemsProcFunc->main is called with the parameter $params 
array.
$params['items'] = &$items;
So you have to fill out the $items there.


/**
	* Perform user processing of the items arrays of checkboxes, 
selectorboxes and radio buttons.
	*
	* @param	array		The array of items (label,value,icon)
	* @param	array		The "itemsProcFunc." from fieldTSconfig of the field.
	* @param	array		The config array for the field.
	* @param	string		Table name
	* @param	array		Record row
	* @param	string		Field name
	* @return	array		The modified $items array
	*/
function procItems($items,$iArray,$config,$table,$row,$field)	{
	global $TCA;

	$params=array();
	$params['items'] = &$items;
	$params['config'] = $config;
	$params['TSconfig'] = $iArray;
	$params['table'] = $table;
	$params['row'] = $row;
	$params['field'] = $field;

	t3lib_div::callUserFunction($config['itemsProcFunc'],$params,$this);
	return $items;
}
