Can you please elaborate what does this mean in term of the IP Catalog FIR II parameters?
What clock do you suggest i use for the FIR? (I have 4 x 16bit samples on each 72MHz tick)
What "Clock Rate' and "Input Sample rate (MSPS)' should I specify in the FIR wizard?
My FIR should be "Single Rate" with interpolation 1 and decimation 1, correct?
Will my input and output avalon streaming path be 16 or 64 bits wide?
I am sorry if my questions are pretty basic, the documentation is kind of confusing to me.

option 1:
clk = 72*4
sample rate = 72
you need to serialise your 4 streams from 72 domain to 72*4 domain serially and input to fir. The fir should be set to 4 channels and will show on the output the channel number.
option 2 (if applicable) use one channel but 4 parallel inputs or 4 instants of fir (though with no sharing of resource) and pass your data as it is on 72 rate with filter clock set to either 72 or 72*4(to save resource) and you should then get enable as 1:4
