I looked at your board. The 0603 position on teh back of the board looks good. One thing: Why not put a couple of 10uF tantalum caps at strategic positions along the PWR/GND busses? Perhaps one at each power connector, and one in the middle? Or -- better -- 10uF at each power conn, and then a 2.2uF on teh back side for each SOIC row pair? You really want to have some bulk decoupling, and for a bus topology like this it helps to distribute the capacitance rather than lumping it in one place. Don't forget to derate the Ta voltage by a factor of 3. That is, if your VCC is 5V, you need at least a 16V Ta cap for safety.
