the krausen (foam at top) usually falls long before it's time to rack to a secondary, if indeed you do rack. If you have a full krausen, it's WAY to early to rack.
Differing opinions here, and other forums - but one prevailing thought is that its really unnecessary to move the beer to a secondary - it has been determined that it is not detrimental to the beer for it to sit on the dormant yeast, and you could be introducing the possibility of oxidation or contamination the more you "handle" your beer. Keep it simple, don't play with it. Let it do it's thing, then bottle or keg.
Read, read, read. Ask questions. Expect lots of differing opinions, as each of us has made good beer different ways and we like to stick with what works for us.
