Chase, I've been using the Medium Tension version. Considering you have no expeience with this thing yet I wouldn't go beyond medium tension.
I can't find that other thread... I described how I'm using the Grip Master. Well vary the finger sequence for better finger independence. But start with doing 'sweeps', going from 1-2-3-4 (index, middle, ring finger, pinky) back to the index finger again, repeat. I'm also doing 'one finger workouts' at times, doing enough repetitions with one finger until I feel some exhaustion, then I would move on to the next finger. Usually I'm starting with my weakest finger and work up to the index finger, then restart from the pinky.
Also, I'm always switching between L and R hands. I've been doing this for 22 years now. I remember one guitarist asked me why I'm practicing my R hand with the Grip Master... Scratching my head... Well I have 2 hands, that's why! And some techniques require the right hand to have some strength so absolutely practice both hands with whatever tools you're using.
Well you need to focus on your left hand then! Haha. It's hard work, nothing to do about it.
