I've messed around a lot with my external GPS module and I can tell you that
1. Phone GPS will still be used, you can do nothing about it.
2. The difference is when your phone doesn't get a good lock, like if you keep it inside your pocket or under the seat, hide it somewhere. You'll see difference and then you'll know that the GPS module is pulling in data.
3. Checking if the module is working ok under linux: "gpsmon -n"
4. I've used u-blox
