When one light is controlled from two switches does both switches need to be 3-way and are the wires connected the same at both switches or are they different?

Both switches require three way switches.

If you have open studs and wiring all new wire to me the easiest way to wire a three way switch system is to run a 12 or 14/2 cable power source to the first switch, then run a 12 or 14/3 cable from the first switch to the second switch, then run a 12 or 14/2 cable from the second switch to the first light fixture. If you have more light fixtures controlled by that three way switch system then just run a 12 or 14/2 cable from the first light fixture to the second light fixture and keep on going from light to light until you have all the light fixtures tied in a daisy chain manner from the first light fixture.

In the first switch that has power in it wire nut the two whites together, nut the bares together and include a pigtail to connect to the green screw of the switch, the black wire coming from the two wire with bare power cable connect to the black or brass common screw, then connect the other black and the red wires coming from the three wire cable with bare to the other two screws of the switches not caring which screw goes to which wire.

In the second switch do the same as the first switch except the black of the two wire cable is the cable going to the light fixture.

Now in the light fixture just connect black to black and white to white and bare to green or bare.

Hope this helps
