In order to reduce taps, you must increase the transition bandwidth. Use the filter design tool to get a feeling for this. Note that this is basic signal processing knowledge, if these things are unclear I recommend you study a DSP textbook. For recommendations, see the gnuradio.org wiki and the 'suggested reading' section.
