Something else I wanted to add in, after I posted:
Remember that any damage has a chance of breaking your Bind, even a Dia for 1 damage. Poison II will not break a Bind. I've solo'd plenty of Energetic Erucas as RDM/BLM, stacking on Elemental Enfeebles as well, /NIN isn't the answer to EVERYTHING. In some cases, /BLM or /WHM is more useful, or even /SCH might also be useful, but my /SCH isn't finished, and seems heavily limited to the 60 second recasts on Light and Dark Arts.
Learn your distances as well, for casting from max range. I try to leave Gravity off many NMs I solo, usually only on the pull, and if Bind wears off quickly, will I re-apply it. If you can afford to cast from max range, that's more "safe" time, to cast whatever else needs casting before the mob reaches, i.e: re-applying Bind, or breaking Bind from max distance, etc.
A macro for gear swapping just to avoid being locked in place by the casting animation is also largely of benefit, as you often don't want to be forced to stand still, even for an instant. Learn the casting speed of your spells in your normal gear you cast those spells in, so you can move just an instant before, for more rooms (you can see this in a lot of BLM videos, on Youtube or Stage6 if you want to look)
I'm jealous of your Morrigan's Cuffs

And well, a lot of your other stuff, but I severely gimped my mage jobs for a few months to finish my Ares's Cuirass XD If you have practice with BLM solo, this shouldn't be a big adjustment for you.
