The sound engine of logic is better than Fruity, the box version of Logic Studio is about €400,- , fruity around € 280,-. For just 120 extra you can create a proffessional sound. I use Fruity for 4 yyears now, and i have the fruity syndrome, nice ideas, sounds crappy.
In a short while I'll be using Cubase for mastering my tracks.
With a book you can't create songs in 1 day, this might take some time.
Books and forums can give you good basic information, but making tracks also depends on your own creativity and some dirty tricks you won't read in a book.

See logic as a car, it is a very nice basic thing, but you want airco, cruise control and all the other extra's.
This all wil cost you some extra money, depending on what you want. But remember, cheap OR very expensive aren't always the answer to your problems.
That is another problem, because what kind of instruments give the sound you are looking for, also depending on the kind of music you want to create.
good luck!
