To get the filenames, use:
var files = document.getElementById('inputElementID').files;
Using jQuery (since you already are) you can adapt this to the following:
$('input[type="file"][multiple]').change(
function(e){
var files = this.files;
for (i=0;i<files.length;i++){
console.log(files[i].fileName + ' (' + files[i].fileSize + ').');
}
return false;
});
