Jeremy,
A power reading of 0.1, 0.2 or 0.3 is only residual noise on the power
detection circuits. Since you do not have Q7 and Q8 installed, your
real power output is zero.
Yes, go ahead and change Q11 and Q13. That is not certain to change
anything, but it will do no harm.
A slightly lower than normal bias voltage for the PA transistors is not
a problem, but if it is higher than 0.64 volts, that is a problem that
should warn you not to install Q7 and Q8 until it is resolved.

With the tuner disconnected, I'm still getting 600mV at the base of Q8 while
doing a tune. The display on the radio shows power of 0.3.
