Well I would first get rid of the grains in your diet including tortillas. Then try to get your carbs under 100g per day to start. Get more protein and don't necessarily look at ratios or calories.

There's no way to do Paleo halfway. It's either you're Paleo, Primal or you're not (or unwilling to make a serious change). There's no in-between quite honestly. From your questions, I have a hard time believing you've read any book at all regarding this lifestyle.

There are no grains at all on Paleo or Primal, nor are there beans (peanuts and peanut butter), hydrogenated oils (Jif uses hydrogenated oils), or sugar (sugar in Jif too). You can have cheese under Primal however but it needs to be full fat, raw dairy for the probiotics. From what you've said, you have a lot of weight to lose at 246 lbs. I'd suggest limiting your carbs to under 50 a day with only occasional fruit (2-3x a week at the most) to induce your fat-adaptation, which occurs after eating strict Paleo for three weeks. I'm also 5'10" and was 183 when I started this journey on January 9th. I'm down 25 lbs already. If you keep your carbs under 50, you'll lose a lot faster. The second phase is the slower losing phase which is between 1-2 lbs a week where carbs are kept under 100 grams but it expands your choices in regards to your veggies and fruits. Between 100-150 grams a day is the maintenance phase in which you won't lose, especially if you eat a lot of fruit. And if you consume between 150-300+ grams of carbs, you'll gain weight.

The macronutrient ratio is something like this 70% fat, 20% protein, 10% carbs. For me this means, my BMR is 1546 as a minimum. My percentages are set to get 93 grams of fat, 88 grams of protein (because I work out 3-5 times a week), and 53 grams of carbs a day. Sometimes I get more fat, protein and carbs but try to not go over 100 grams. The macronutrient ratio is based on the premise that the types of calories you intake burn differently. It takes 9 calories for every gram of fat, 4 calories for every protein gram, and 4 calories for every carb calorie.

How much protein are you getting? Should be between 15-30% for Paleo/Primal, on the higher end if you're an athlete.

How much fat are you getting? Should be between 60-80% for Paleo/Primal

Carbs come last between 10-20%, sometimes more depending on your goals but the total number of carbs shouldn't be above 100 grams a day if you're trying to lose. Even in the maintenance phase, that many carbs (above 150 grams daily) are unnecessary. Keep in mind that even if MFP tells you that 10% of your 1800 daily calories are carb calories, you should not be eating 180 grams of carbs on any day if you're doing Paleo/Primal. It doesn't calculate it to keep your carb count static at a max of 100.

When you say "burn more than you take in is the key is losing", it doesn't apply here. Please read the books you purchased. They'll save you a lot of time and questions you might have regarding why Paleo eaters already eat less than the average SAD dieter. It has to do with satiety coming from fat and protein, and trusting our own bodies to eat what we need, hence the lack of calorie counting. I count my calories to make sure I'm getting enough. There are some days I go way over my BMR but other days I struggle with getting enough. I've been trying to get at least 1600 a day and that's why I use MFP. When I first started, I was getting a lot less...somewhere around 900-1100 a day.

With all that said, Paleo/Primal takes a lot of willpower in the beginning but once you get used to it, it gets easier. There are a lot of really good books out there as well as websites. Take the time to explore the reasoning and science behind the diet by reading constantly if you can at least for the first few weeks.

peanuts are a legume not a nut. legumes (beans) are right behind all grains and sugars for the "no" list. No one expects perfection, but grains, sugars and bad oils must be completely eliminated if under your control. Seriously give the "no-grain-at-all" thing a try for 3-4 weeks.

almond butter is a fave of some who can't give up on the peanut butter easily.

And yes you must get under 100g of carbs in order to begin your journey.
If you eat meat, veggies, nuts and the occasional fruit (for now), for a couple weeks, you will begin to see an impact. At first it does take some concentration, but soon you will not imagine ever wanting those things.
