So, can I assume that would part of the key to using the waterfall to tweak your response...adjusting the bandwidth of the filters to modify the waterfall plot?
Exactly, though centre frequency and gain might also need tweaking for best results.

What is the ideal decay rate (or realistic desired decay rate where sound quality is not compromised - i.e. we obviously aren't listening in anechoic rooms), or do we just want it to be relatively even across the frequency response?
Ideally decay would be uniform across the band, for domestic rooms the ideal is thought to be around 250-300ms, though there is more tolerance of extended decay times at low frequencies than high. Look for discussions about RT60, a measure of decay time (more relevant for large venues but often discussed in the context of domestic rooms also).

I guess could also be said that boost in particular should be performed at as wide a bandwidth as possible, with subsequent cuts to included peaks, instead of boosting individual dips - which is more likely to introduce ringing?
Right again
