I'm in a loud place right now so I can't really listen right now, but here are a few suggestions. Keep in mind that I too wish to formally study composition; I've learned everything I "know" by reading stuff on Wikipedia and books that I bought
-Music Composition for Dummies (it's not exactly the biggest authority, but it's a great place to get started)
-Learn EVERYTHING you can on music theory. It helps. A lot.
-Yeah learning counterpoint from Fux Gradus is really good.
-Study a lot of compositions you like and try to find techniques the respective composers use. For example, I love Rachmaninoff and I notice like a lot of the cool harmonic effects he achieves are by holding 1-2 voices still throughout a progression and moving another. For example, in the very last part of Rachmaninoff PC 2 Mov. 2, he holds the G# and B constant in all of the voices, and moves the piano melody from E to D# to C#. Find things like that. You need to know what to look for though, so a basic knowledge of harmony/composition helps.
-A TON of analysis. I'm more of a see what people do and learn their tools and use them on my own/develop my own tools kind of a guy.
-Tchaikovsky's book
-Schoenberg's book
-Any other book you can get your hands on do some googling
