I haven't played it but the T32-A does seem like a really good tank(I'm considering trading in my IS-6 for it). The T32-A is simply a T32 with the stock turret and an autoloader, and as such it has solid hull armor, turret armor that can bounce shots but isn't reliable, and a very good gun (it deals 960 damage per clip with a decent 28.5 second reload as well). It's also unique for the fact that it has a 10% Free XP multiplier (as opposed to most tanks which only have a 5% multiplier).
Also, I would certainly say it's worth trading the Fatherland in for unless there's some other tank you'd prefer to trade it in for. The Fatherland isn't really a good tank, has a very high gold price, and was given away for free, and as such it's pretty much the best tank to trade in for another tier VIII premium.
