The right amount of Dex and AR for my HC Zealot

How should I prioritize stats, skill points and gear as my Zealot is getting ready for late game?

My lvl 82 Zealot has 105 base Dex and roughly 4k AR when using Zeal. Depending on where in Hell difficulty he's zealing, 75-86% of his strikes hit. When using Vengeance to deal with physical immunes he's got about a 67% chance to hit. That's painful.

Gear: Oath, Tal Rashas Mask (10% dual leech and 60 life is not that bad, thinking hard about what to replace it with), HoZ, String of Ears, Gore Rider, Laying of Hands (useless except for the fire res since I'm hitting 4 frames per Zeal strike even without the gloves). I've got some half-ass crafted and rare jewelry that add some AR, but I feel like it's not enough.

I also have a bunch of left over skill points. I've put only about 10 points in Holy Shield, which is enough for me to hit Max Block with HoZ. This made me feel like I could afford 5 hard points into Blessed Aim for the hidden AR-bonus it provides. Defiance got a couple of skill points as well to buff my defense with Holy Shield, but I still have 5 free points and I'm racking up more as I go up in levels.

So...

If I get a decent Ravenfrost and level up closer to 90, will I get a high enough chance to hit to settle, or should I keep spending hard skill points on Blessed Aim and prioritize dex over vitality as I level up?

I planned out this build to use an Oath Cryptic Sword, Andariel's Visage and Laying of Hands. It turns out I misunderstood how IAS works and I don't need Andariels Visage or Laying of Hands to hit a very fast breakpoint. Is there something other than Guillame's Face and Dracul's that I could use in those slots to boost my AR in a worthwhile way?

General advice: to hit mobs better, you need both buffin your AR and debuffin mobs defence. Don't forget about modifiers such as "- enemy def", "ignore target defence", some Battle Cry from your CtA, or your own Conviction aura, etc.

Do I really have to get a Grief or spam Battle Cry to get >90% chance to hit? I was thinking I'd get there with a Ravenfrost and some nice rolls on crafted jewelry.

pretty sure investing in Dex is not a very good way of boosting attack rating, which is why regardless of melee build or not every guide recommends not to invest in Dex unless its to meet gear requirements or to max out block. in your case, you should probably just try to get attack rating through charms or other items since you already have max block

Where do I dump my excess points then? Does the higher defense warrant maxing out Holy Shield (and Defiance on top)? Or should I splurge on Resist Lightning and lightning charms so I can do Uber Tristram with 80% lightning resistance while under Conviction?

im not an expert on Zeal build so usually i just refer to guides like this, but after maxing out Fanaticism, Zeal, and Sacrifice, and enough in Holy Shield for max block, you can just toss points anywhere really.
If your goal is to be able to do Ubers then investing a bunch of points into Resist Lightning to boost max lightning resistance is probably a good idea, its even recommended in this guide, but just remember you do need a ton of resistance to make use of the max increase for ubers since youll need around 300+ resistance to max out after -125 from Conviction and -100 from Hell difficulty mod
