hi C Johnson, glad you are enjoying the MGS blog and find it useful for your own project plans. i will try to expand on your questions from your post:
1) the second grenade launcher is omitted on the later MGS which features the skate mounted MG with gun shield as the shield would hit the launcher mount. i have seen some pics where the second launcher is missing even with the older axial MG mount. the mounting base is still there on the turret but the launcher framework is left off.
2) the wire conduit that is made from L angle metal runs wiring to the additional lights that are on the front slat portion. additional lights were required to help drivers at night as they found the standard lights going through the slats insufficient.

discussion purposes only
the above pic shows the headlights and L angle to hopefully clarify this as the lifting hooks are used to mount the square supports for the angled forward slat panels so the original headlights could not be moved to the attachment lift points.
the guard rails for the headlights are omitted as the slat armour protects the headlight cluster.
3) the arc slats on the sides where the turret would otherwise hit is broken up into 2 portions on the left side. i will be working on this section after i finish the back slat portions as this is off the chart in the "complicated" spectrograph. hopefully once finished it will clarify this area.
later MGS' appear to have an additional "lip" around the 2 left hatch edges. perhaps after production began they found that these hatches distorted during explosions and needed additional material on the perimeter to keep them from buckling. for whatever reason, the AFV Club should be updated to have these added.
4) the rear slat is simple yet complicated. each element is fairly simple but getting everything in the correct proportion and placement will be complicated. the rear section opens in a "double gate style" with drop in pins to keep it locked. the lower slat is mounted directly to the doors. i will take some clear pics of this when completed.
5) the slat armour has four orange hazard lights mounted and i chose to make them out of bits of round styrene and plasticard of various thicknesses. they are so small i plan to paint them to look orange/clear rather than fuss with clear styrene which is harder and more brittle to shape. i will be adding all the wiring that runs to them as well.
i think once the model is painted all these tiny details will be clearer. i don't believe my camera can show these small pieces well when they are all white.
hope this helps and thanks Mr J for the great discussion on this project. this is the kind of thing that makes this forum fun for me. cheers, bd.
