Welcome! :wavey
Well, first off, there is a link here on the board that defines all of our often-used acronyms. The ones you asked about, in particular:
BF: Blackfire, a sealant with supposedly carnauba-like properties (I've never used it)
AIO: Klasse All-In-One, a very, very good paint cleaner. It also adds a layer of protection by itself that rivals many waxes.
SF: Uhhh.... I dunno, I can't think of anything for SF. Maybe you meant "MF" (microfiber, a popular type of cloth here)? Check the acronym sheet, though. Not sure. :nixweiss
Good luck in your competitions! I'm sure that most people here will agree in that the vast, vast majority of your results will stem from your prep work; that is, using Pinnacle Souveran, a $70 paste wax, over a crappy finish is not going to get you drop-dead results. However, removing as many imperfections as humanly possible (swirls / minor scratches, contamination, and that sort of thing), polishing the paint, glazing (if necessary, really), and topping that with a wax will look great. There's many routes you could take, though, like:
Wash > Clay > Swirl Removal > Meguiar's No. 7 (which you may be familiar with; you'll still want to do a swirl removal prior to this, though, since it is better to get rid of (most of) the problem rather than just hiding it) > Meguiar's No. 26 or P21S
Wash > Clay > Swirl Removal > Klasse AIO > Klasse SG > P21S
Wash > Clay > Swirl Removal > Wash > The Zaino System (I'm not a user, can't give specifics here)
There's lots more.
Of course, you will definitely want to make sure you wait the prescribed amount of time before you start waxing / sealing fresh paint. :xyxthumbs
