Tom,
The K1 options can be installed in any order.
As far as the D2 diode, that is entirely your choice, and should be
based on your local noise situation.

I've completed my K1 RF Board, 4 Band Filter Board, and Antenna Tuner Board,

I discovered the KNB1 Noise Blanker is still available and just received it.
(Thanks, Elecraft!)
1) I'm assuming I should install the Antenna Tuner first, then install the
KNB1 - is that correct?
2) As to replacing D2 (1N4148) WITH D2A (green LED) - what are the
arguments for and against that? As I will be using the K1 in a variety of
locations in the Field it will obviously be impractical to install the diode
on site if I discover high noise level interference there. Why not just
initially install the diode to raise the threshold in order to cover worst
case scenarios?
