I did a paper on this at Yale: The spacecraft could, in theory, continuously accelerate in a straight line, forcing objects inside the spacecraft in the opposite direction of the direction of acceleration. Most rockets already accelerate at a sufficient rate to produce several times Earth's gravity but can only maintain these accelerations for several minutes because of a limited supply of fuel. Theoretically, a propulsion system with a very high specific impulse and high thrust-to-weight ratio could accelerate, producing useful levels of artificial gravity for long periods of time. In addition, constant acceleration would provide relatively short flight times around the solar system. A spaceship accelerating (then decelerating) at 1g would reach Mars in 2–5 days, depending on the point in the synodic period. In a number of science fiction plots, acceleration is used to produce artificial gravity for interstellar spacecraft, propelled by as yet theoretical or hypothetical means.

How does Serenity maintain what appears to be an Earth-normal gravity while in interplanetary space? it doesn't have any rotating parts, (there is a ring around the end of the ship, but thats the outer showing of the engine) and it's doubtful that humanity would have invented any kind of anti-gravity in the 2500's. How do they do it?

All this hard banking -- when the gravity drive and actual gravity start working against each other, it tosses your lunch about a bit.
