I have the same model of phone and using Windows 7. I am using Odin 3.7 without any issues at all, as far as the USB drivers go I first downloaded them directly from the Samsung website and when I initially plugged my phone into the computer, Windows searched and installed drivers also which confused me since I already had drivers installed, but I went with it and have had no problems. You probably already know this but remember to turn USB Debugging on.
