As far as nutrition, 2300-2400 is quite low if you are going to be that active - that would be my "cutting" calories, and I'm only ~110lb! Make sure that you actually KNOW what your Maintenance is, and go from there. If your NUTRITION is NOT correct for YOU re fat loss, then it won't happen - NUTRITION is the MOST IMPORTANT factor in fat loss, and whether or not you are successful (or not) with your fat loss will be primarily dependent on your nutrition!
I seriously recommend reading The 3 Keys to Fat Loss for comprehensive advice and information re nutrition and training for effective and successful fat loss.
