..probably one of the biggest gains in my mind is to learn to totally relax your wrist AND thumb; both physically and mentally. Guitar set-up will make a difference just starting out, but ultimately should not have that great of an impact and will become more personal preference... . I'd suggest shaking-out your wrist and thumb for awhile, almost exagerating it. At some point you should feel totally unencumbered and not self-conscious by relaxing yourself physically; then work on the 'feel' of slap bass which will take you to the 'right' level.
You have to feel the emotion in order to get funky, then you'll naturally relax; you'll WANT to slap. In the 70's cover band I'm in, when it's time for the dance set, if I'm not feeling it, I can't get my groove-on. Consequently, I may not slap as much.... . You'll be supprised how much of it is mental. Get one of those cheap keyboards with drum loops built-in and play against it. You already have the instructional videos. Don't get discouraged.
