I am designing a FM receiver and the first module is BPF. I have decided to use chebyshev filter but i am finding it difficult to design it. The only information i have is:

Resonant frequency (i.e. frequency of signal received): 140 MHz
Q factor : 14
fL: 135 MHz
fH: 145 MHz
Bandwidth: 10 MHz

How should I approach to design my Chebyshev BPF? How is the order of it is determined? Any help is appreciated!
 

To make it a complete chebychev filter specification, you need to add passband ripple and stop band attenuation. Order can be only determined from this specification. Q is a parameter of the second order filter building block ("biquad") not the filter itself. A chebychev filter is comprised of multiple biquads, each with different center frequency and Q.

Most people will use a filter design tool or Matlab for the calculation. But you can derive the filter parameters also from basic chebychev polynomials, can be found in classical filter design textbooks. (Presumedly it's over your head).
 

So should I assume passband ripple and stopband attenuation values and move on with my calculations and design the filter? If yes then may I know how exactly the assumed values will affect my filter design?

Filter parameters lower and upper cut-off frequency ("fL and fH"), ripple factor, stoppband attenuation are translated into filter order (number of second order building blocks) and center frequencies and Q of individual second order blocks.
