Problem with FIR II core

Hello, I am trying to use 11 taps symmetrical FIR using the IP Catalog in Quartus 14.1 My data are in signed Q.15 format with sampling rate 288MHz. I get the data in packets of 4 samples (...

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.
