I've been on the Paleo diet now for 6 weeks. Strictly adhered to its rules for the first four weeks but have recently added small amounts of rice due to a problem I was experiencing - my legs burn going up just a few flights of stairs, my arms burn with relatively few reps of a weight I used to be able to lift easily. Initially I assumed my body was just switching energy sources and I would soon be feeling "freakin' awesome" as this was the desired outcome. 6 weeks in and I don't feel any better is there a usual time frame for feeling more energetic and not "burning up" so quickly?
You probably have almost no glycogen in your muscles to fuel anaerobic activity. Eating 130g net carbs a day would replete liver glycogen only. If you're lifting weights or doing sprints, you need to exceed that amount. Your other alternative is to eat a lot of highly ketogenic fats like coconut oil, but I've never seen any evidence that ketone bodies can be converted to glycogen. Odds are that even with a heavy coconut oil intake, you're in a highly catabolic state with gluconeogenesis converting muscle and/or dietary protein into glucose, and even then it's not enough to replete glycogen stores completely.
What is your diet like? I'm assuming fairly low carb? A lot of people need some carbs if they're working out. Try a cyclic-low carb with most of your carbs coming post workout in the form of sweet potatos and the like. Carbs aren't the enemy, they just need to be quality and used appropriately.
I would submit this question to Robb Wolf @ www.robbwolf.com. This seems interesting enough to make it onto his podcast. He loves quirky stuff like this. I won't even take a stab at this one b/c you've got some serious problem going on under the hood if you're getting lactic acid type pain after small amounts of activity. Godspeed.
From the list you have there, I see very little FAT!!
Fat is the key to all of this and making your body feel well. You are almost in what is called the Rabbit Syndrome. You are starving your body of it's basic need.
A little coconut oil and fats from the nuts aren't cutting it. Eat some Bacon! Cook your eggs in Bacon fat, Eat Avocados or guacamole, Fat is what greases up our joints, and make our brains function properly. More good quality organic meats, bacon, avocados, coconut oil (drink it straight 1 or 2 shots, yes shots) of it daily is great for your skin and your body. More eggs. Salt is key too...make sure you season everything well, There is little salt on this eating plan due to the removal of all processed garbage, so season your meats well.
And yes...DRINK LOTS OF WATER.

You may need more magnesium so that your muscles don't make as much lactic acid. Also, anytime you increase protein intake in the diet you need more magnesium. I take this supplement myslef: http://www.wellnessresources.com/products/magnesium_muscle_mag.php
