I'm sure Chapman's "Piloting" will give you the official best available answer, but Ill tell you what I did when faced with this last summer.
Approach the buoy 45 degrees off the wind slowly so that you will come up to the buoy with it on the windward side of the boat and next to the middle of the cockpit right off the gunnel.
Drop 'er into neutral and go out and immediately reach down and put one end of 30 foot or longer line 1/2" or so in diameter through the buoy.
The boat will start to drift away downwind. As it does, lead the line with both ends in your hand to the front of the boat.
Tie off both ends of the line independently. Be sure they will not be cut by the anchor, etc. One end can go to the center cleat and be dead ended there, the other lead through that cleat and then tied there or elsewhere.
You want the loop and the front tying arrangment so that you can simply drop one end of the line and pull it through the buoy's loop without untying any knot on the bouy (akward).
Tie the ends so that you can quickly untie them in an emergency and remove the whole line so you don't catch it in the prop. (This is a good idea for your bow lines in general-keep them short enough they cannot reach the prop if left overboard accidentally.)
If your anchor is in the way, you may have to feed the lines through the bow eye used for trailering to get a lower purchase.
A nylon rope is more elastic and therefore better than a dacron one for shock absorbtion when anchoring.
They make a tricky slicky pole with a clever hooker-dooker deal on the end that will pass a line through the eye from a little distance away, but if you can pull up close as described above, why bother? Also, my guess is that the eye on the buoy would have to be fairly large for this cutesie contraption to work (?).
Here's a look at the babe itself:

Now go read Chapman's and see how to do it right!!! (?)
