Having trouble designing a JFET input stage in a Multistage Transistor Amp
The design is a bit off in some areas, first the FET biasing scheme is fine but its a bit of downside as you will limit the input impedance, you should aim for a self biasing scheme, FET will not give you a gain typically more than 4 times so its up to the later BJT to exact the gain. 

Let Re in both stages be split to 2 resistors, with the lower in parallel with bypass cap, your lower frequency limit is calculated by the bypass cap \$ value = \frac{1}{ 2*pi*R*C} \$ where R is the resistance in parallel, for high frequency limit you should connect a cap between collector and ground or Vcc and calculate the value the same but with the resistor being the collector resistor. 

For gain assume Ic = 1mA, Ve = 1V so Re = 1Kohm, since gain is Av= -Rc/Re1  just set the Rc to a value like 2K and a gain of say 10, then Re1 = 200 ohm, since Re total  = 1 K then the bypassed resistor is 1k -200 = 800, assume that first stage a gain of 2, second stage a gain of 10 and third stage a gain of 5, then total gain is 2 * 10 * 5 = 100

For the FET use a self bias scheme with 1 - 10 Meg resistor and set the current for example to 1mA, since you want it to work in active mode, then RgIg - RsId - Vgs = 0; since Ig = 0; then RsId = -Vgs, Vgs = -4V, Id = 1mA, then Rs = 4Kohm, you can as well split and do the bypass trick to get a higher gain = -Rd/Rs otherwise it would be Av= -gmRd

I forgot to add the higher frequency limit capacitor, add it in the last stage from collector to Vcc before the decoupling cap, for feedback take a line from R8 top through a resistor and capacitor up to R14 top (input of Q1), I not that experienced with Feedback but I think it sould do a shunt-shunt feedback.
