Azimut (ADV?) did a set of lounging resin figures , not the in-action type included in the Tamiya kit. I have a set I might part with, drop me a PM if interested.
Like Steve said, most of the Verlinden accessories, except the ones with the ground molded in.. 

 , will fit quite nicely.
The radar mast and lights could really use some wiring, and the life saver ring looks much better with a twisted copper wire rope and lead foil wraps.
The searchlight sticking up through the canopy needs an L-shaped handle and wiring, as does the light next to the twin 50's. The tire bumpers for the sides could use holllowing out as could all the mg barrels.
I put 2x M16's on foil mounts inside the cockpit armor, after looking at Apacolapse Now. 
There are detail pics in an old Verlinden magazine of the engine compartment but that was beyone my abilities.
Still, I won a few awards with the kit 6-8 yrs ago.
