We are currently doing a tear down and rebuild of several CNC machines at my workplace. Most of the machine parts will be sent out for sandblasting and painting using your RustSeal. Some of the larger pieces will be painted in-house. Our maintenance area where the painting will occur is not the most remote area of the plant and people are working in the near vicinity. What kind of fumes does the RustSeal emit and how intense are they? Do we need any Personal Protection Equipment when working with the prep chemicals or RustSeal? We will be using brushes and rollers to apply the RustSeal.

Also, do we need to topcoat the RustSeal or will it be fine by itself?

If you are not spraying but are applying by brush or roller, you should be wearing gloves and eye protection. If it is an enclosed area (like a building) you should have moving air around the job area ... fans, open doors etc. Care should always be taken to minimize the exposure to solvents. Most of the solvents are released within the first 2 hours. After that there is minimal release. Yes, PPE should be worn as per directions and cautions on the labels. As your CNC machines are inside the RustSeal will be fine as long as you are happy with the color.
