I am just finding this thread. I have some insight as I am in the process of doing this quest right now.
The Welding Mask is a "quest" in Geffen. Bring 2000 zeny and 50 Steel to geffen_in 144 166 and the npc will make you one.the RMS guide on it
The Transparent Plate is ID#7355 (@ali 7255 if you only want those).They drop from the RED Dimiks. The other colors drop different colored Transparent Plates.
jupe_core is probably the best map for these
Venatu drop the Rusty Screws too.
For the Iron, Coal, and Lanterns, I found Pitman in ein_dun02(or for_dun01) to be great at knocking out all 3 plus, Old Picks.and they drop the steel for that welding mask
Cog Wheel is in the game as Cogwheel. Apocalypse drop those in juperos_02There's tons of Venatu there if you still need some of the screws
The Research Charts are from the mobs in lhz_dun03
I don't have the time to make a pretty guide post for this but I had no clue how silver mvp cards were acquired until I found this. I found the other guides to be very helpful and easy to follow.
