Well, I'd love to say that you get a comprehensive manual when you register, but that isn't the case. There's a PDF/Word "getting started" document that's worth a read (esp. to get your head round automation), but it's probably not as good even as the Help.
FruityLoops is a deceptively powerful program though, but you may have to do a little research to get the best out of it. Each of the generators / effects has a help sheet (albeit a few lines on an html page). Have a look through all the folders in the browser - there's some tutorials hiding in there. Some of the demo tunes show how some functions are used, e.g. x-y controller.
Once registered, you have access to on-line forums tech support and loop talk, plus some on-line tutorials and FAQs. I would definitely suggest spending some time there and you will get a fast response for any queries you make. I would go careful on there though, as they have a tendency to be somewhat sarcastic over there, heh heh.
It took me a while to figure out how to do things like running multitimbral instruments, multi-sampling with layers, and exporting patterns to midi.
(btw - Paul re triplets : I think you're suggestion would change the time signature, but each note would last the same length. Triplets changes the relative timing of notes so some are closer together than others, like ddd-ddd-ddd-ddd instead of d-d-d-d-d-d-d etc - though I have a feeling that's not quite right, so someone might have to correct me here).
