Nice review.
Although I don't have all the references I'd like at hand, I can still answer to some of the questions raised in the text based on what I do have.
You mentioned there are markings for the bombs in the kit, I presume there is a similar (or the same) decal sheet also having stencils, as on the earlier
German boxing of the kit? I'm under the impression that the planes in Finnish service rather quickly received Finnish language stenciling, so one might want to check their references.
I wonder why there is only decal options mentioned in the instructions, as the decal sheet also includes markings for MT-437. The lynx's head and yellow number nine should go the tail, like
this. (< that's my somewhat recently finished 1:72 kit of the same particular aircraft)
Continuing with the decals, the national markings look fine, but should have the backgrounds painted with the so called "DN color" (~RLM 65) by the timeframe given in the instructions. (the order for the dimming was given January 1944)
I'm not sure whether there was a distinct "early" or "late" type of the G6, but yes, some of the later production aircraft received the wooden, taller wooden tail & rudder (the same as later 109 variants, like G10 and K4), hence their inclusion in the kit.
The painting and marking guide has the planes' tail configuration correct, so choose your parts according to that. Also, choose your canopy following the markings guide. (note that MT-451 shows the correct canopy in the sideview drawings, the Erla type)
The wing cannon pods were originally fitted to MT-451, as correctly shown in the markings guide. (The pods were removed from many planes during the war to increase maneuverability. IIRC, they were removed from MT-451 too at some in the summer of 1944)
Every G6 came with the 300 litre fuel tank mounts, but they were usually removed from aircraft not doing missions requiring longer flying times (like night fighting for example).
Some Finnish G6s were also fitted with the bomb racks, but unfortunately I don't have references about them at the moment.
I hope this helps.
Edit: let's try again, my whole post didn't show for some reason.
Yes, it worked now.
