he Sun (and therefore the Earth and Solar System) may be found close to the inner rim of the Orion Arm, in the Local Fluff, at a distance of 7.94±0.42 kpc from the Galactic Center.[13][14][15] The distance between the local arm and the next arm out, the Perseus Arm, is about 6,500 light-years.[16] Our Sun, and thus the solar system, is found in what scientists call the galactic habitable zone.
The Apex of the Sun's Way, or the solar apex, refers to the direction that the Sun travels through space in the Milky Way. The general direction of the sun's galactic motion is towards the star Vega near the constellation of Hercules, at an angle of roughly 60 sky degrees to the direction of the Galactic Center. The sun's orbit around the galaxy is expected to be roughly elliptical with the addition of perturbations due to the galactic spiral arms and non-uniform mass distributions.
It takes the solar system about 225-250 million years to complete one orbit (a galactic year),[17] and so is thought to have completed about 20-25 orbits during its lifetime or 0.0008 orbit since the origin of humans. The orbital speed of the solar system is 217 km/s, i.e. 1 light-year in ca. 1400 years, and 1 AU in 8 days.

The center of the sun actually orbits in a very small circle, causing the sun to wobble a little bit because of the tidal forces from the planets. The sun, and the entire solar system orbit the center of the Milky Way Galaxy.

The Sun has an orbit; it orbits around the center of our Galaxy, the Milky Way. It takes the Sun 225-250 million years to complete a revolution around the Milky Way.

The Sun and our whole solar system have an orbit inside of the Milky Way galaxy. The Milky Way galaxy is a spiral galaxy and our solar system is on the outer edge of it, so we kind of just orbit around the center of the galaxy.

Around what, the sun? That's impossible.
The sun orbits around the black hole in the center of the galaxy.

Well, technically we don't actually revolve around the Sun and neither do all the other planets. The planets and the Sun all revolve around a barycenter at the center of our solar system. The Sun, being as massive as it is, doesn't get pulled much at all by the planets so it appears as if the planets revolve around the sun. They all revolve around the barycenter though. So the answer to your question is yes, the sun revolves around the barycenter in the middle of our solar system as well as it's orbit around the galaxy.

The sun may have an orbit. The sun's path will be influenced by the nearest black hole.

it orbits the center of the milky way

Yes it did, it still does, and it will continue to do so for a while to come.
For example, see http://en.wikipedia.org/wiki/Milky_way, look about a quarter of the way down the page at the diagram on the right ("Observed structure of the Milky Way's spiral arms").

Did and does. It follows a large ellipse around the galactic center.
