So my questions are, how extensively can the roots be trimmed without causing problems? Which parts of the root can/can't I trim? How regularly can this be done?

when i had a serious root issue, i trimmed off about 12", and left a 4" stump of roots hanging off the bottom of my plant with about few weeks left till harvest. this was an extreme measure. and i was still able to get a healthy harvest. so,------>imho<------ i would imagine that you can trim them as often as they need it. just don't start at the top!!! and, as long as you trim the bare minimum, it shouldn't effect the growth rate hardly at all.
most soil plants are tall as their roots are long. roots in a hydro solution really don't have to search for nutes, because they are present all the time and completely envelopes the root itself top to bottom, unlike soil, where most root growth is directed towards and by its' food source. its the way i understand it....
