Advents are not a good place for new players, sadly. You can somewhat get something done if you can handle Expert, but what you should be focusing on is getting yourself ready for Ultimates ASAP. This basically means prioritizing:
1. 0-Star Eidolon for 100 Jewels, so that you can pull Jewel gacha a bit sooner (also makes you just slightly stronger)
2. Kamihime weapon ticket
3. 20 pots, these are a limited resource and should be collected
4. Maybe the Premium ticket and 0-star SSR weapon
5. Soul Points are good for whatever you have left, you need to get the basics ASAP (Gawain, Cass, Mordred, Dartagnan, Joan, probably in that order)

Anything more than that is of course a good thing, but you should aim to fill #1-3 on both Advents at the very least.

Now that Naberius exists, it is unlikely we'll see bosses who heal themselves. It has happened before, Phoenix used to heal HUGE amounts if you didn't just let her buff expire.

It's not really the opposite. Mordred gives the boss an extra bubble to fill. Like, Ragnarok Rahab has just 1 bubble, so without Black Propaganda, she'll use her Overdrive every second turn or EVERY turn in Rage mode. Meanwhile, Satan's third skill takes one bubble away from the boss. So, for example, you use it on turn2 and you just gained yourself an extra turn before the boss can use her Overdrive. Combine this with Black Propaganda and you'll get a lot of extra time on your hands.

And note that on some bosses, you'll want to keep Satan's third skill to manipulate the bubbles when you want to. For example, if a non-Rage Overdrive is not a problem, just let the boss use that. Only use it when it'd stop a boss from using a Rage Overdrive, in that case. For some bosses, it's the reverse - you want them to only use Rage Overdrives. Adapt accordingly.

Sanahtligs toolbox has the answer to that. The last ones are extremely expensive, and it's unlikely you'll be able to buy them unless you're running Ultimate. Even then, you might need to be potting. And I don't think that using pots before you can do Ultimates is wise. Then again, if you do, you'll get stronger faster, which means you'll be able to do Ultimates faster.

Your Light team is pretty good. Once you get some Raid events under your belt, you can spend the Gems you gain from there (completely eclipses all other Gem gain, really) to buy normal Gacha, then level up Light weapon skills. You'll want to get as many Light Hammers from the Light Disaster raid, both Normal and Expert drop it.

The next Light Events are early November (Advent) and late November (Raid). I'm not sure if you can do Ultimates for the Advent, but if you can get there in time, you'll be in a good spot. However, do note that from the Raid event, you NEED that Eidolon. Preferably maxed. At that point, if you've been farming a Light weapon grid from Light Disaster, you should absolutely be ready for almost anything the game throws at you (Ragnarok's excluded).

Oh, and there will be two Union events soon, so I hope you're in a strong Union.
