I'm about the same height as you with a slightly longer inseam.
I ride a 62cm frame. For me I find it perfect. I have always preferred larger frames as I feel cramped on smaller ones.
At the end of the day if you're comfortable that is all that matters really. If you rode a smaller framed bike you'd no doubt still have the seat and bars set to something like the levels you have them at now. All you're doing is filling the `air space' that a smaller frame would give you with frame, for what would be effectively the same riding position.
In conclusion, bike size/fit looks good. Let your body and your riding tell you what is right, not what the `experts' tell you to conform with today's trend for an aggressive/competitive fit.
