Retrieving entries along with all the custom field data

What would be the correct way to retrieve a list of entries with all their relevant data programatically?

I have a list of entries I have imported via DataGrab, problem is I now have to create member accounts for the relevant people associated with the entries. About 140 of them.

$this->EE->load->model(‘channel_entries_model’); $query = $this->EE->channel_entries_model->get_entries($channel_id);

The above query just returns entry_id etc, how would I grab the custom fields?

Thanks for any help.
