I watched the videos but I didnt know acrylic and the floating was necessary. Figured like I see the stones being used would be fine. My sheets are 3M, color/micron/grit

Forget about the .3u film. You will not enjoy shaving with that edge even if you can make it work. Nobody uses that. Not many, anyhow.
You may want a coarser grit for setting the bevel. 30u works pretty good. Make sure it is LAPPING FILM, not polishing film or micropolishing film or polishing paper or polishing film or any other deceptive nomenclature that actually means "don't try to use this for your razors, but please, by all means, buy it from me". 12u will set a bevel but it is slooooooow. Read this thread, again, beginning to end. Trial and error over the years have built up the knowledge base and caused best methods to change somewhat.
When you are first starting out, NO detail is unimportant. There are a bagigazillion ways to do this wrong. Odds are against you finding the handfull of ways that will do this almost as good as The Method. So stick with The Method until you have several good edges under your belt or you will just be chasing, never catching, that elusive Method edge while other guys come in and get a killer edge their first or second time at bat.
