Destruction on Protectors - Yes, Immolate everything in sight and Havoc on cooldown. I tend to prefer to use Havoc for Chaos Bolt in this scenario where nothing returns embers, purely because Shadow Burns that don't crit are pretty underwhelming, and if you burn 3 embers you may have wasted a lot of potential damage. Use your judgment on your procs/whether its worth burning 3 embers.
When to use GoSac - I use it on everything; good use of embers with procs/cooldowns will see GoSac pull ahead. Especially considering how ember rich most encounters are in SoO. Maybe use a pet on IJ heroic if you use the knock back and hide strat.
Spec for IJ heroic - Don't go Demo for two reasons. 1) Your ilvl is still quite low, and you may find that you don't have enough secondary stats (haste/crit) to fuel you fury generation. Destro is still more than viable on this fight, and you can go with GoSup if using the knock back strat. Havoc the mines with incinerate for extra ember bits. Destro also feels the safest spec with ember tap which can help your healers in a pinch.
Immerseus - MF vs KJC - Just stick with KJC. Add damage isn't really that big of a deal, if you feel more comfortable with KJC then use KJC. It's hard to quantify a damage difference when it depends on where your comfort levels lie.
Backdrafted Chaos Bolts - Generally a bad idea. I do use it on my opener to get that first Chaos Bolt out faster. It's probably worth it in your situation as you'll likely have Dark Soul up then too, and missing those procs will be a huge chunk of that Chaos Bolt's damage. The higher haste you run the less of a negative impact this has, I think!
Ember Master and Chaos Bolt - Are you tracking the ICD of ember master so you know when it will proc. I can always refresh Immolate and get a Chaos Bolt off each time it procs. Usually Chaos Bolt > Immolate > Conflag can all be squeezed in. Again, depends on your haste.
That was a really really quick response, some stuff other people will likely disagree on.
