Mike, use this stack up non critical gnd critical -5 gnd critical +5 (better if this was ground) non critical
or gnd critical non critical power gnd non critical critical gnd (if power switch critical and non critical) two reasons why I say put the critical in the center of the board. First your board vender will be able to control the thickness of the traces better, when they plate the board. Second your board will be a lot more quite. You will then only have to factor in the etch factor to keep you impedance.
