About the performance capabilities... According to the research I did for a JSF presentation, the AF required the JSF to perform at least as well as an F-16 or they would not purchase any planes. The last statistic I saw had the number of aircraft ordered by the AF at 1700 or so. I don't think they'd spend all the money for a plane that didn't perform up to specs.
About the thrust... The F-35B is supposed to put out equal amounts of thrust from the jet and the lift fan. The number I saw reported was over 19,000 lbs at each output - so somewhere between 38k and 40k total should be about right. I don't know what happens to total thrust when the lift fan is disengaged though, anybody else know?
The engine is not exactly the same as the one in the F-22, but it was derived from the F-22 motor.
