No power in outlets after changing light switches
You need to get all those neutrals together

Your problem is that you split the neutrals up instead of bundling them together; thus, power has no way to get back from the other switch, the lights, and the outlets to the utility.  The easy fix is to turn the power off at the breaker, unbundle the white neutral wires, bundle them all together with a big enough wirenut, button things up, and turn the breaker back on, then things should work.
