It's all about the money. You pour in some money and time, then sprinkle some intelligence into the bowl, stir until consistent. Bake to solidify, and wallah; photographer.
The quality of said photographer really is based on the quality of the ingredients.
So that being said, easiest part is getting the gear right?
I tell you what, you're never dissatisfied with the best.
So look at the prices on Google, then decide how much you want to spend towards one of these:
D3x
D700
D300s
D90
Now you need a portrait lens, grab a cheap one of these
Nikkor 50mm f/1.8
Then one of these:
AF NIKKOR 85mm f/1.8D from Nikon
It will work good for indoor poor lighting, outdoor portraits, even your kids dancing on a stage in a play.
Now you have your camera and lens, but need light. Until you have used a quality flash, you don't know what you are missing.
Pick one of these up at a minimum, in order of presedence, based on your budget:
Nikon Sb-900
Nikon Sb-600
So you've got camera, lenses, flash, and now you need accessories.

Then maybe some time on here and a local college course or two!
That should get you started.
