Should I go to a barber or stylist?
I'm going to keep this short and sweet, since I think the last OT was too cluttered. The biggest difference between a barber and stylist is that one has a license for a straight razor and the other doesn't...for the most part. Forget about terms like "nape" or whatever. Bring pictures to your stylist or barber, that's the bottom line. And preferably one for every head angle. You don't want your stylist to ask if you want a disconnected fringe and have no answer. Also, consider the following: the longer your hairstyle is, the more suited it is for a stylist or salon.
It's up to your stylist to form your desired style to your head. It is important to take advice from someone who does this everyday. However don't lose sight of your dreams!
IMO, Pinterest sucks. I use Tumblr and Instagram.

Products and styling
Ask around here for your desired style. I once used a huge range of products, but now all my needs are solved by a hair dryer with a diffuser, Baxter matte clay, and some volumizing mousse. I forbid wet look products from my restroom p much, but obviously different strokes for different folks.
