As far as the assembly goes these were the issues (they were small) and comments (mostly just about the manual).
1. I was missing a 3/8 nylon spacer used as the y-axis end stop bumper in my kit. It was the only thing missing and I was able to use the extra 1/4x1/4 and 3/8x1/8 inch spacers stacked together to get the job done. There were a plethora of extra parts, which is a nice touch. (After posting this, I found the spacer I needed at Lowe's, cut it to length and installed it.)
2. Speaking of those parts, I have a small nit to pick about the belt idler assembly. It would be nice to have the slim wrench required to tighten this provided with the kit, even if it was just a cheap stamped one. I used needlenose pliers, but just wished for the proper wrench. Also, page 8 of the manual should probably double the number of components listed and state you need to make two of the idler bolt sub-assemblies. A revelation from the tips thread

I'll add one - it worked out OK, but if I was doing it over again once I confirmed I knew how the assembly of the idler bolts would go I'd have screwed the bolt into the frame before I put the bearings and clip on - that way I could tighten the bolt with any old adjustable wrench instead of using needle nosed pliers because my wrenches wouldn't fit because of the bearings.
3.Be careful of the orientation of the parts when you disassemble the control box. I had to do this twice because I had the bottom flipped and it only goes together one way-which I wish I had found out before installing the Rambo.
4. In the manual you may not need page 29,30, and 31, since they have already installed that stuff for you now! Yay!
5. The spool holder page in the manual should list the screws needed as M4, not M3.
6. No instruction in the manual for the Z-axis hand knob.
7. The instructions for mounting the fan sub-assembly and extruder mount to the stepper are not included. This page should be in the manual, don't you think?
8.The instructions for the Z-axis M4 end stop screw and jam nut are not included. There is a MG video here on setting the z-axis stop

9.If you are assembling this from a kit, do yourself a favor and print out the exploded diagrams to refer to while building. It's a big help. Hey MG staff, it would be fantastic if the exploded diagrams were integrated into each corresponding step in the main assembly manual. It would have been a great help to see how things go together. The drawings are better references to use than the photos in the manual at certain steps.
10. The SD card reader wiring in the manual is white and "marked" with correct orientation marks. My wiring harness is multicolor and three of the wire have gold marker on them....so yeah, I am going to have to email tech support about how to orient the wire going into the reader.
update-I figured it out on the next page of this thread.
11. Instructions or just a picture mentioning how to clip in the glass build surface. I feel if the part is there in the kit, no matter how simple or obvious it end usage seems, there should be a picture of it installed.
12. It is a bit inconvenient to have to jump to the M2-(assembled) instructions to see how the printer setup is finished. Once you finish the manual for the kit OR the assembled printer, I feel you should be at the same place in the process.
13. No instructions for installing the Kapton tape. Again, it was included, let's document it, mmmmkay?
So, as I said earlier, nothing big, just a few nits to pick, mostly with improving and updating the manual a bit. I have just finished the wiring and finishing touches which took two hours for a grand total of 5.5 hours to get it ready to plug into the wall and computer.
I'm pretty happy with how it's going so far!
-update: I am updating this list a bit as I go, so there will be several edits.
