The orbital physics used is always impressive. I assume some velocity adjustment is done by the drone to intersect with the asteroids? Or are the orbits that precise?

They are very precise. Take note of this video, recreating one of the real missions that took place four decades (!) ago. It recreates the orbit in Kerbal Space Program with a mod called Principia that enables N-body simulation using original mission specs and calculations.

It seems kind of crazy that they would visit the Greeks, then do another flyby of Earth in order to visit the Trojans. I wonder what the cost-benefit analysis was of doing that versus just sending separate probes to each of those (which presumably would need a lot less fuel)?

Is this one of those things where this really is the best and cheapest option and my intuition of orbital mechanics is just wrong?

The spacecraft will make corrections with its onboard thrusters over the course of the mission.
