Earliest Dsmash can begin (assuming frame 1 is the first frame of the total action [shielding, plucking, etc.]):
Split-second Shield (optimal) - begins on Frame 15, can input Dsmash on 9+ (1-8 produces a spotdodge)
Pluck - begins on varying frames (see explanation below*), can buffer Dsmash normally (10 frames before the end, which is the entire pluck most of the time)
BONUS TIME: Simply releasing and Dsmashing (optimal) - begins on Frame 15, can input Dsmash from frame 7 onward (comes out as dash attack if input on 1-6)
*AN EXPLANATION:
The FAF on Olimar's pluck changes depending on the terrain. The Dsmash will start on the FAF if it is buffered properly.
FAFs:
120%- Frame 9
100%- Frame 9
80%-- Frame 10
75%-- Frame 10
70%-- Frame 11
40%-- Frame 14

I really really hope this all made sense. Please let me know if it didn't.
Also, what kelumhi said. I'm not sure of the specifics, but Dtilt is kind of mediocre to bad for comboing. That Falco had opportunities to get out.
I don't know. I played with a G&W for the longest time and I think it's a +2.
IIIRC, Denti believes it's an even match-up and he has UTD Zac to play with, so he might be someone to ask.
