What do I really need?

I could use a little help! I am a stay-at-home mom of 2 and began running and doing light weights along with using MFP last year to lose my baby weight and get into shape. Now I'm doing free weights 3x a week and running about 4 miles a day 2x a week (so working out 5 days a week). With the new year I made a goal to run a half marathon in May, along with a 5k in April and so I've added a third day of running to do my long runs and have a sixth day of exercise.

I've been wondering lately if I'm eating enough and getting the right %'s of carbs vs fats vs protein as some days I feel completely worn out and with the half marathon prep I want to be sure I've got my nutrition right! I currently have MFP set at Active since I've been working out 5-6 days a week and I'm constantly chasing the kids, doing housework, etc. so most days I sit to eat otherwise I am up running around until 4:30 am until 9:00 pm or so! I've lost all of the weight that I want to lose but would love to get a little leaner. After bumping my exercise goal from 5 to 6 days on MFP my current daily calorie goal is 2,000 - without my exercises and depending on the type of daily exercise it bumps up to 2400-2500, most days this is really hard to achieve! My calorie breakdown is set to 45% carbs, 30% protein, 25% fat.

Do these numbers sound right to any of you, am I doing this right?! If there's any additional information needed let me know, I truly appreciate any and all advice! Thank you so much!
