So you have a DSLR? If so, get a cable release.
Night photography needs a tripod, regardless of style (IE, big legged, or gorilla pod, or even a small bean bag) as you need long exposure n a steady camera.
You want the best equipment you can get (no shit Sherlock). Tho, it doesn't have to be sooo expensive.
The thing you want most tho..... PRACTICE PRACTICE PRACTICE PRACTICE PRACTICE PRACTICE.
read books from photographers you admire, and copy.... Under rules of photography, you can hire the same models, wearing g the same clothes, on the same island as sports illustrated, but it's not wrong, cos you took the photo!
I don't do anywhere near the photos unused to take, but I do enjoy taking pics still.... Even if just the cat
