heh... it wasn't easy, and I didn't get it all. I selected the area of the wood that I wanted to recreate, selected the wood color on the left, and filled it with that color (on a new layer). Actually, I made the area a little bigger so I could mask out the edges with a soft brush. I took the healing brush, sampled the good wood on the picture layer, then painted the grain and such back in on the new layer.
Long story short, lots of cloning, lots of healing, and lots of trial and error. I find it useful to have two windows of the same document open, one zoomed out so I can see how it's going to look, and one zoomed way in that I work on. You can open another window for the same document by going to Window > Arrange > New window for ***.
hope that helped some.
