How are the taps supposed to be set for Analysis Filterbank,
particularly in GRC?

I was wondering about the same thing earlier this year.  Have a look
at gr-pager/src/  Some of the code:

taps = gr.firdes.low_pass(1.0,

        if options.verbose:
            print "Channel filter has", len(taps), "taps"

        bank = blks2.analysis_filterbank(40, taps)
        self.connect(self.src, bank)

Just remember to connect every output of the filterbank to at least
something.  Otherwise none of the outputs output correct data.
