Miller's book is pretty nice. The docs also include filter-graph abstractions
to profile filters similar to yours but a bit more powerful in that they also
graph the phase response.

Other than that, IMO Julius O. Smith's  DSP Guide is the best reference as far
as "musical" filters are concered. 

Some nitpicks: your patches use some objects not available to me, namely [f+]
and [lbang].  I assume they are trivial objects, why didn't you use use the
standard [loadbang] and a [f][+] counter? Also the signal sends etc. are
global, which makes it impossible to use the objects to compare two filters
side by side.
