Career Advice and Plan

I am a GN nurse (I will find out wednesday at 8:00am if I am a RN, BSN) from Abilene, TX
I worked on a Cardiac Step down unit/CICU for the last year as a PCT, and been hired on as a RN. We have both the step down unit, and a six bed Cardiac ICU (mostly post cath's, etc).
My orginal plan was to move to Houston, TX and work at Texas Children's Hospital starting on a general pedi floor and moving to the Pedi ER. Things did not work out, and I had to stay in Abilene, TX to get more experience.
One of my career goals is to become a Family NP (start in 5 years).

This is my current plan. I will work on my Cardiac Step down unit (we have a whole lot of overflow of med-surg patients) for the next 2 years. In about 8 months I want to get cross trained on the Pedi floor at my hospital. I will work on both floors (one week cardiac other pedi something like that). I'm planning on getting my ACLS in the next 4 months, and my PALS before I get crosstrained. I am leading a children sunday school class for austic kids. At around 2 years from now I will move to a Pedi ER in Houston.

Is this a good career path/plan for me? I think my floors will give me a lot of good experiences for my FNP.
People are telling me I should get my Adult CCRN. Would this just be a waste of my time in the big picture?
Should I get my Pedi CCRN?

Thanks for any advice!
