I've seen several different methods for accomplishing this, but I was wondering if there's a way of doing it that is best? Also, somewhat related, but is delta in milliseconds?

That's what delta is for. It calculates the amount of time that has passed since the last frame (tick) in milliseconds.

You mainly use it for lag compensation or interpolation but you can use it for anything. It's basically a fractional frame.

EDIT: You can also use it as a lagometer. If the ms goes higher than the tick rate, that's how you know that your game is under load.
