Not sure why you wiped your post.
Learning audio just takes time. It took me a few years to pick up on what I like and hate. Until then just try everything you can. Just remember that nobody can tell you something is good if you think its crap. Your opinion is all that matters in the end.
The FLC8S' will teach you most of what you need to know about the type of sound sigs available. Basically it'll cover 90% of the IEM's on the market's sound sig for the most part.
Oh and I'm far from considering myself a seasoned poster.. Unless you mean my age then maybe. I'm only 34 though so maybe? My knowledge of gear is not small but it's not large either.
Feel free to PM me though or anything if you have any questions.
