The axis is the imaginary line running through the north and south poles that our planet revolves around. Earth's tilt refers to the fact that the planet does not sit perfectly straight in relation to the solar plane but rather tilts slightly to one side.
The earths orbit around the sun is almost circular.

It depends on your point of observation. It may appear to curve if you are stationary with respect to the surface of the Earth, though with respect to the travel of the object it will (with ever-so-slight perterbations by the sun, moon, etc.) fall directly toward the center of the Earth.
The influence of earths rotation is called the Coriolis effect. The coriolis effect causes wind to curve instead of going in a straight line.
