json is a javascript object. So there is no need to "decode" it. However, it looks like you are using jquery. There is a nifty function for retrieving json data:

jQuery.getJSON(url, senddata, function(returndata){alert(returndata.cool);})

or

jQuery.getJSON(url, senddata, function(returndata){mybigfunction(returndata);})

mybigfunction(data)
{
    myvar = data.cool;
    alert(myvar);
}

or you could also do it with $.ajax as you mentioned:

jQuery.ajax({
    url: url,
    dataType: 'json',
    data: senddata,
    success: function(data){mybigfunction(data)}
});

mybigfunction(data)
{
    myvar = data.cool;
    alert(myvar);
}

The "callback" is a function that gets called and passed the json data returned from the url.

You will 'ice' baby... ermm... sorry for the corn.

The getJSON method is rather short and handy. Have a look at the links for more details.
