Don't spend too much time agonizing over that DVD because setting up floating systems for tropical fishing and prowling beaches for SB, blues or false albacore is an entirely different game.
For the fishing you described, you'll be using (or should be) an intermediate line 90% and throwing a variety of fly sizes.
After 40 years of trying almost ever system imaginable, I've settled on 4-6 ft of 30-50#mono connected by a tiny 50# spro swivel to 3-5' of 12-20# flouro.
I generally use lighter butts for lighter lines. The tippet depends on conditions such as water clarity, fly size, weather, etc.
I use different leaders systems for floating lines and sinking heads.
