1st, decide if you want star trails or not. Generally you need to be less than 30 seconds for pinpoint stars, and a lot less with a longer lens (600 "rule").
For interesting star trails you need to be well over a minute. In between times tend to look like mistakes/ blurry.
2nd, do want dark skies/no moon, or bright sky/big moon for landscape lighting? Relatively few stars can be seen with moon; Milky Way is only visible with very little moon.
Key hardware is a solid tripod and a lens you can focus in the dark. You might want to prefocus in light, then tape the lens at actual infinity. Have a very low power flashlight so you can check your settings without blinding yourself. Tripod techniques: mirror up, 2 second delay, remote shutter, intervalometer, etc. Practice in daylight. For very long exposure, use black cardboard for shutter and a manual timer.
Bug spray, pillow or chair, music, etc Be comfortable and have fun!
