I'd like that very much!
Here. They are on mediafire and are quite large in size together.
Though their size is nothing compared to dem professional sample libraries (which can range from 10 to 200 something gigs).
Sure you can't complain.
I'm afraid you need to find or buy FL Studio yourself. I'm not gonna help you with that.
Or you can use some of those free DAW's.
Just google: Free DAW program
Or something. Just make sure you can use VSTs and soundfonts in it.
Hope that helped.
