Just as a suggestion, you might want to start with something a little smaller and easier, to learn to shoot ILS approaches with, like a C172, until you get the basics down pat. The big tubes are a lot more unforgiving on the approach and you will get frustrated trying to learn using one of them.

It's more then just getting to the vicinity, you need to enter the approach using the correct procedure or you will never get aligned in time to complete the approach.
