On a package of 2 40W 48" standard GE flourescents the lumens are listed at 3150. That would mean for a typical 2 bulb light strip you get 6300 lumens from just standard flourescents. That seems kind of high relative to the lumens of CFs. Does anyone know if the 3150 is for each bulb or total for both?

That is the lumen output for a single bulb. Those numbers are kind of deceiving though. That number is the initial lumen output, however after the bulb has burned in, the design lumen output is usully about 10% lower.
