Your Kreb's cycle looks pretty good. Yes there is a slight a slow down at Aconitase, which could be blocked by heavy metals, but its still functioning pretty well.
The most notable thing for me was the almost universally low B vitamins. They are cofactors for so many important metabolic processes, including energy metabolism, that I am surprised that glycolysis and Kreb's cycle are as good as they are.
Low B vitamins are probably responsible for most of your abnormal results.
Glycolysis looks ok (decent pyruvate etc) but you are having problems with feed into the cycle.
Your not burning fatty acids well (elevated adipic, highish suberic) which is carnitine related and could in turn be B2 related.
The high beta OH butyric indicates you are going into ketosis - not burning carbohydrates well.
The very low cystathionine means transsulfuration will eventually be compromised (lack of starting material) even though for the moment you are producing enough cysteine and glutathione. This could well be B2/B6 related.
Here is Rich's thoughts on interpreting the test - lots of detail for you to contemplate.
