You can use the iPhone app Starwalk to visually see where the Milky Way will rise and travel.
For dark skies, an exposure I like is ISO 3200 f/3.2 for 33 seconds, roughly. Then there are plenty of tricks you can use in post to make the Milky Way pop. For example, try boosting the Blue luminance channel in ACR. Pump up Clarity at bit. Drop color temp to roughly 4800. Etc.
But the main thing is to find a dark place with clear skies.
