I was eating very low carb and high protein, high healthy fat and for the first time ever my fasting blood glucose was too high (98) and so was my insulin (9.0). I got some advice here and from my nutritionist and ND and added more sodium and a few more carbs to my diet.
I also got an at home blood glucose monitoring device (the one recommended by Cris Kresser) and so far I am totally and utterly confused.
All three of my two hour post-meal readings have been higher than my one hour post meal readings.
I cannot find any explanation of this. And Im unclear what Im supposed to do about it since I am eating more protein and fat then I am carbs and my total carbs are still well under 100grams a day

I've had a similar experience. For a while, I was overweight and was a Type 1/2 Diabetic for 9 years, Insulin-dependent with a poor, high-carb diet for 6 years.
After of now, I'm in great shape and have been Paleo for almost 2 years, eating a very similar diet to what you posted. However, even after adding in carbohydrates and doing a Ketogenic + Carbohydrate cycling plan, I've still noticed some high fasting sugars and post-meal sugars.
A few things I've noticed...
It's obvious that Insulin sensitivity is definitely increased when carbohydrates are restricted over a long time. I've noticed this, but at the same time, it's NOT a bad thing, especially if your looking to improve body composition. In that case, meal timing can really be used as an advantage.
Regardless of these issues, I'm pretty sure I still have some Insulin resistance. Maybe not much, but I have a feeling that what I lost in that 9+ years may not have been 100% recoverable. Not sure it ever will be, 100%, but everyday I'm monitoring it and doing my best to keep trying to do it.

If you are on a ketogenic or very low carb (VLC) diet (e.g. with 50-100gr carb/day and/or eating ketone producing MCT oils such as coconut oil), you may have a dilemma of having high Blood Glucose (BG) despite eating LC: If you are keto adapted, that is, your body is using ketones and even though you have sufficient insulin (say >5 microU/ml) your body tries to keep your BG higher than necessary, e.g. above 100-110 mg/dl. That is your BG set-point is always high. If you try to lower the set-point to say 80s, by water Intermittent Fasting (IF), then your body starts to convert your muscles into glucose to keep its high BG set-point. So, you may have a slightly lower BG, but you lose some muscle mass. Having a high set-point has many other problems, e.g. if you eat something with a little bit more carb, say a small fruit, your BG shoots up to 130s and stays there for hours. This may be due to something called "Physiological Insulin Resistance (PhIR) ...
