Hello and welcome HondaLou. I was away for a while and just got a chance to check my manual. The only red light on the right side I can think of is the oil pressure warning light that is in the tachometer face. It should be an oil can shape. When the engine starts, oil pressure will turn the red light off, but don't be alarmed (yet).
The green neutral light is independent of the gear position indicator, so likely the problem is the neutral switch. Both oil pressure switch and neutral switch are underneath the engine, and both have a single wire - light green for the neutral light and dark blue with a red stripe for oil pressure.
AND both wires are share a 2 pin connector. As they leave their respective sensors, the 2 separate wires are covered with a black sheathing, and combined into a subharness to the 2-pin connector (black). This routes along the lower side of the clutch cover, and plug into the main harness under the right side panel. There are 2 metal wire clamps along the bottom of the clutch cover that may have pinched them.
It is likely that the wires were pinched to ground, which would cause both problems simultaneously. You can unplug the connector, and neither light should go on. If you unplug the connector and unplug both sensors, there should be no continuity to ground. If there is, it's a sure sign the harness is pinched.
