Answer 1

You are accessing your Order__c object incorrectly. You should be pulling the order off of the StandardController using the getRecord() method.

Your controller's constructor should look something like:

public class myController{
    public Order__c order{get; set;}  
    public myController(ApexPages.StandardController sc){
        order = (Order__c)sc.getRecord();
    }
    // Other logic here
}

You should read up on the proper technique of Building a Controller Extension. There are some other things you may want to consider as well. For instance, I see you have a hard coded Account Id in your code. This is considered bad practice. You should also look into setting up proper transaction control utilizing the Database class to setSavepoint() and rollback().

Answer 2

Right now you are referencing an object named "Order__c" in your VF, but the variable is named "order" in your custom controller. You need to match the field names on your VF page to your controller extension. If you want the data from your VF page to show up in your custom controller, update the variable names.
