I know I'm a little late to this thread, but for the OP and anyone else who follows through, I dug up some before-and-after shots from building my own pond, just to show the stark difference the plants will make. I also really hated the initial look of my pond after putting rocks around the edges, but I had a little previous experience with it and knew things would grow in.
Here's an initial shot taking in May 2011 as I was still laying rocks around the new pond. They are just kind of bare, out there in your face, looking way too pristine...
By October of that first year, I had a number of plants really filling in around the edges and breaking up the solid look of the rocks...
And finally, this is from July of 2012, only a year after all the plants were put in...
As you can tell, depending on the plants you use, you may not even be able to see your rocks in some places after the first year! Absolute placement of your rocks will not matter at all, however you do want to ensure that your rocks are placed solidly, so that animals stepping around around the edges don't push the rocks into the water.
Hope that helps ease your concerns?
