I'm trying to follow this, you have lights that aren't working and plugs right?
If you have an issue with lights and plugs I'd suggest checking in the ceiling boxes. A lot of electricians would source through the a ceiling box then down to the switch and one to feed the plugs in the same room. My guess is you lost connection in a J box. Are you checking power from positive to neutral or positive to ground. If the neutral wire is broken you'll show no voltage when checking positive to neutral but you'll show voltage going positive to ground with a volt meter.
