You can use a two way switch in a one way installation. Use the two connections on the one side, not the top two.
The wires are hard to pull out, the screws don't make any difference to them, the screws are an alternative connection method only, many people feel more confident screwing the connections down than they do with the press-in wire connections. Just pull hard on the wires, it can help to twist the switch so that the wire rotates slightly in the hole while you pull. Grasp the wire though, don't depend on the wire holding in the box while you are pulling the switch away. These grip very tightly. This is a good thing as it makes the connection by bighting into the copper.

Hey all, i bought a light switch today to replace one of mine in the wall and i bought a three way one instead of a one way. Now the ones that i have in the wall are a one way, or at least thats what i think there called, they have two wholes on the back where the wires go in to verses the one i bought witch has three. So can i still use the one i bought or do i have to get one like the one thats in the wall? Also when putting the light cover back on over the switches how come those dang little wholes are so hard to line up? Like i will have one screw in there and it will line up just fine then when i try to put another screw in the screw goes in at an angle. I got it back on and everything is fine but why are those wholes so hard to line up? Oh, one more thing when i was in there, i couldn't manage to get the wires lose from the switch. I unscrewed the screws that were in the sides of it and tryed to pull them out but it wasn't coming lol. How hard could i pull before i break something?
