The amounts you're eating are fine, and the variety is good as well.
I should mention that not only wild animals but also hunter-gatherers prize the organ-meats above all other meats. In some cases, in times of plenty, they'll just eat the organ-meats and leave the rest. A good example are those killer whales hunting the baby (grey?) whales in the eatern pacific - usually, all the killer whales eat is the fatty tongue of the calf, ignoring the rest. A human example, would be the royal courts of Mediaeval Europe where the kings and nobles getting first priority/right of choice re the organ-meats.
My opinion is that organ-meats are essential for important things like fertility(tribeswomen, according to weston-price) would routinely seek out the organ-meats to ensure maximal health for their offspring(indeed, I strongly suspect that the falling western sperm-count is directly attributable to the lack of organ-meats in the modern diet). However, it is possible to maintain adequate, if not optimal, health on a diet of zero-organ-meats. Obviously, though, if one is seriously ill at the start, it would be more beneficial to have some organ-meats so as to speed up recovery.
