-Tracks must be researched before mounting everything that adds weight

This is wrong. One can add the (heavier) '90mm Rifled Gun', plus a selection of 200kg of equipment combinations [eg. gun rammer, stabilizer+GLD, or vents(+Co2 filled tanks)]

Ammo costs are listed wrong

For top values, the HE ammo is listed as '4400' credits each, this is probably the HEAT shell price. The HEAT price is probably the correct value for the HE shell.
