Dave, I installed a KT-34XA in 1983 at my previous Colorado location and
grounded all parasitic elements to the boom primarily for lightning
protection and to hopefully minimize precipitation static.  The antenna
performed very well and BTW still holds the USA record for the CQWW SSB  
Contest on 28 MHz set in 1988.  I also grounded the outer conductor of the
coax feedline at the point it connected to the KLM balun.  I have no idea
how to model this on EZNEC but would imagine you could at least assume
straight elements the physical length of the linear loaded elements.  Hope
this is of use to you and others.
