Answer 1

You have to call the remove() method of the store, passing the record you want to remove. So, call the each() method to iterate through the store, check the status of the record and remove that if it is equal to 2:

Ext.getStore('MyStore').each(function(record) {
    if (record.get('status') === 2) {
        Ext.getStore('MyStore').remove(record);
    }
}, this);

Answer 2

This way you only call remove once:

var store = Ext.getStore('MyStore');
var records2del = [];
store.each(function(record) {
    if (record.data.status == 2) {
        records2del.push(record);
    }
}, this);
store.remove(records2del);
