I hadn't noticed that Arm's Length also gives slow to enemies. Now I have to find a place for it on my quickbars which are already too full.

Superbolide is a difficult one since it sets my HP to 1. I definitely don't want to use it from near full health since that just creates extra work for the healer. But if I try to save it for an emergency I may end up using it too late and die anyway. It's honestly the most disappointing of all the invuln abilities due to the self-damage. At least Holmgang and Living Dead can be safely used just in case, even if they can't come close to the OPness of Hallowed Ground.
You're pretty much there with cooldown usage. Learning to adjust based on kill speed is a skill you'll gain over time but I personally like to stagger my cooldowns so I'm at about ~30% mitigation for the start and middle of a pull when the most enemies are alive, and then dwindle down a little near the end as enemies die. Generally this means using one medium cooldown (Rampart, Arm's Length etc.) + one small cooldown (Reprisal, Aurora etc.), or one large cooldown. (your 30% or your invuln). Mitigate as best you can during the high damage periods and then hold a little when you know you're safe.

As for Superbolide, it's definitely awkward but it's actually the second most useable one in dungeons - one idea is to set up a Macro you can hit which will announce you plan to use Superbolide as your first cooldown next pull, and then hit pop Superbolide around ~25% - you don't need to be 100% optimal, and it lets the healer know they don't have to use anything on you except to get you back to full. Honestly, the most important quality a tank can have is a willingness to learn so you'll be fine - out of interest, what were the trash pulls that wiped you while levelling?
