Answer 1

The best way is that you have to use the geocode api of google like as

http://maps.google.com/maps/api/geocode/json?address=karachi&sensor=false

If the limited access then no need any google api key.

In response, there is a json object "location" inside "geometry" where lat and lng present which will give you a co-ordinate of your entered location (karachi)

geometry: {
  bounds: {
    northeast: {
      lat: 25.2703106,
      lng: 67.46845189999999
    },
    southwest: {
      lat: 24.7519801,
      lng: 66.6609568
    }
  },
  location: {
    lat: 24.8614622,
    lng: 67.0099388
  },
  location_type: "APPROXIMATE",
  viewport: {
    northeast: {
      lat: 25.2703106,
      lng: 67.46845189999999
    },
    southwest: {
      lat: 24.7519801,
      lng: 66.6609568
    }
  }
}

Answer 2

You need to use Place ID tag to get Lat/Long
