Answer 1

In your column configuration you can define editor for column. There you can set Ext.form.TextField as column editor. In textfield configuration you can define max length limit by maxLength config property.

Column configuration:

{
   ...
   editor: new Ext.form.TextField({
       maxLength: 25
   }),
   ...
}
