Answer 1

I will do my best to use the vernacular of your coding in this example

note i am using coldfusion 9.0.1 and jquery 1.9+

jquery/javascript

           $('#lstTiers').on('change', function (){        
               $.ajax({
               url:'Ajax-test.cfm',
                       data: {'method': 'returnSomething',
                              'Tier': $(this).val(); },

               success: function(json){
                   if (json != '' )
                var vx='All';
                   $.each (json, function(k, v){

                       vx+=''+v.client_name+'';            
                   });
                   $('#lstClients').html(vx);
                   }

               }); //end ajax()

       });

Coldfusion

    
        
Select * from Clients WHERE Tier = #arguments.Tier# ORDER BY 1 
    
    

heres the thing, you need to see what return type json format is giving you, if it is coldfusion json, you would change the jquery each iteration to $.each (json.DATA, function(k, v){

i do things in the MVC way , and like my json to be standard non CF output, so heres an example of my code

controller

    
          
           
        
        
    select distinct d.init_contact_staff, initcap(e.pref_name_sort) name  from ben_activity_dtl d
    inner join entity e
    on e.id_number = d.init_contact_staff

    where d.nd_event_id =  
    
                                and d.request_status_code =  
                            
    order by 2 asc
