Answer 1

The issue is with the data you're returning from server. With that store configuration you must return a json formatted like this (note that records fields are different that yours)
{
"success" : true,
"count" : 2,
"myTable" :[{
"id" : 1,
"cod" :"100001"
},{
"id" : 2,
"cod" :"100001"
}]
}
Store's root parameter is where extjs expects to have the array of records, success parameter is something you can handle to display server comunication errors and totalProperty is where you tell to extjs how many total records you have fetched. (Answer based on extjs 4.x, but as i can remember with 3.x is the same)
