Answer 1

Provided that your input values are integers, you can construct a Date instance using them:

var CurrentDate = new Date();
var SelectedDate = new Date(
    $('[id$=txtYear]').val(),
    $('[id$=drpMonth]').val(),
    $('[id$=spDate]').val()
);

//As quite rightly mentioned, January = 0, so if your inputs have the literal number for each month (1 for January) replace the line above with the following, to take a month off:
//var SelectedDate = new Date($('[id$=txtYear]').val(), $('[id$=drpMonth]').val()-1, $('[id$=spDate]').val());

if(CurrentDate > SelectedDate){
    //CurrentDate is more than SelectedDate
}
else{
    //SelectedDate is more than CurrentDate
}
