Well, concerning that list that you requested, it would go something along the lines of:
Maker: Benchmade
Designers: Mel Pardue, Doug Ritter
Sizes: Large (3.4" blade), small (2.9" blade)
Blade styles: Drop point, wide chord drop point, saber grind sheepsfoot, hollow grind sheepsfoot, tanto
Opening mechanism: Thumb stud, oval hole, round hole
Blade steels: 440C, 154CM, S30V, D2, M2
Blade options: satin plain edge, satin partially serrated, black coated plain edge, black coated partially serrated
Handle materials: Noryl GTX, color valox
Handle colors: Black, olive drab, desert sand, camo, orange, yellow, purple, green, blue
And that's only stock options - doesn't include any of the aftermarket customizations you can get (such as the Wilkins scales made of G10, titanium, etc.). Also, I may have forgotten a few options, but I think I covered at least all the most common options.
As for actually finding the right knife, I'd start with picking a size, then a blade style or opening mechanism (whichever is more important to you), then a handle color, then, if applicable, a blade steel. Don't worry about who designed what - think more about the features of the knife, and whatever price range is acceptable to you.
Not to make this post longer, but in case it's helpful in figuring out which models are what, here are some configurations that should be pretty easy to find (also, you could add "SBK" to pretty much any of these model numbers for black coated, partially serrated blades, which would be equally easy to find):
550HG - Black handle, 3.4" 154CM hollow ground sheepsfoot blade, round hole opener, ~$65
551 - Black handle, 3.4" 154CM drop point blade, thumb studs, ~$65
552 (AKA, "Ritter Grip") - Black handle, 3.4" S30V wide chord drop point blade, thumb studs, ~$115
553 - Black handle, 3.4" 154CM tanto blade, thumb studs, ~$65
555HG-YEL - Yellow handle, 2.9" 154CM hollow ground sheepsfoot blade, round hole opener, ~$57
556 - Black handle, 2.9" 154CM drop point blade, thumb studs, ~$57
558 (AKA, "Mini Ritter Grip") - Black handle, 2.9" S30V wide chord drop point blade, thumb studs, ~$105
