Does anyone have any thoughts and/or experience with these plants and
any thoughts on my Nitrate situation. Any help would be greatly
appreaciated.

Any plants, in this case macro-algae, will be difficult to keep in good shape
in a tank with tang. If the fish has access to the plant it will nib on it,
or even uproot it trying to munch on it.

Also, consider the fact, these plants grow in deep sand with quite strong
water wave movement... This water movement is constantly cleaning plants
from the debris accumulating on the plant surface. You will probably not
have sand bed deep enought to properly root this plant - you would need to
hold it upright with rocks, but it will be quite tricky...

How deep is your live sand ? 100lb for 110g tank seems too little for DSB.
Is your tank 4 feet long ? What is the surface area of the sand bed ?
The good way to lower nitrates to amost zero is to have DSB (deep sand bed)
with active worms and other micro-fauna/flora living in between sand grains.
