Any Air force or Navy Pediatric Nurse Practitioners willing to provide information?

I graduate with my MSN as a Pediatric Nurse Practitioner August 09. I am looking into both the Air Force and the Navy, trying to decide which would be best for me. I would love any information from any PNP's in either branch regarding their military career and what to expect as far as assignments, pay, COT training, processing time as well as job satisfaction.
Also, I will be certifying as a Primary Care pediatric nurse practitioner, and that is where my training is. I have not trained in a PICU and want to be sure that I won't be expected to function as an Acute Care PNP. Does this happen? I have a former AF nurse tell me that it was possible.
One more thing (and I know that there may not be any info on this), I am particularly interested in autistic spectrum disorders and developmental pediatrics. I know opportunities may not be available initially, but is there any possibility later down the road to focus on this in the military that you know of? (Are there any new programs, etc)

Again, any information would be greatly appreciated!

Also, did any one else have trouble contacting recruiters and getting follow up?

Thanks again!
