Received and mounted new 8A 12V power supply for the lights, which makes them way brighter, not overheat the power supply, not flicker out occasionally, and not dim the lights when turning on the fans. Also received the new machining vice and drilled (and counterbored) 3 new holes with a 1" spacing. Mounted up everything successfully, and ready for a test run tomorrow. The only caveat is that technically the vice is able to run into some of the z-axis components if the user is not careful, so that is a design flaw in the entire z axis setup.
