Thanks for taking the time to take all those pics.
OK, let's go around the dial.
Weapon: I have to wonder what its original STR was at for you to reroll that. Ideally you would have rolled the natural socket off to +%damage and then use a Gift to put that socket back on.
Ring 1 (Band): Pay special attention to any non-boot items which have movement speed on them (that, Compass Rose, Slave Bonds, Lacuni Prowler, Flavor of Time), as that affix can be rolled into something much more useful. If you kept its original STR value and rolled that movement speed into CC, that ring would be much more useful to you.
Ring 2 (rare): Fine. No RORG?
Boots: Even on boots, it's more useful to put the movement speed to something else and use Paragon points for your movement speed increase. There's not a lot to do with boots anyway so don't despair over these.
Pants: Hopefully you've been burning shards for this, as this should be the easiest thing for you to get in either Akkans or Rolands.
Belt: Probably as good as you can get for now until something like a String of Ears or Witching Hour comes along or maybe even a Thundergods if you roll with Lightning.
Shield: I've had a few of those equipped and I don't think I've ever seen that special actually occur. Does it? I honestly don't know. Tempted to say the socket should be changed to All Res, but it's probably not much different to just put a diamond in there anyway. I think I might have a Helskul laying around, and that would be a much better shield for you given your other item choices.
Bracer: I imagine a crafted Reaper's Wrap would help you out here at least. Bracer is one place where you can always have an elemental bonus and you don't have one here. This is a problem. More later.
Shoulder: Really nice roll here. Up the STR if you must, otherwise it's fine where it stands.
Amulet: If this was 90%+ CHD I'd say keep it, but you might be able to justify losing 64% CHD for a socket to hold a third legendary gem.
Helm: What's this ruby doing here? Otherwise, same as pants - should be easiest to get you a set item here from Kadala or drops.
Chest: Roll Life Per Second to %Life. Decent otherwise.
There's also the question of your build - it seems like you want to do Holy attacks but without +%Holy damage on your amulet or bracer, it's not going to be as effective.
So.
If I were you, I'd hunt out a new RORG to replace that Band of Untold Secrets and try to get 3 each of Akkans and Rolands, as I'm assuming that you're not trying to go Shotgun build at the moment.
Add some people like me (Sillysil) and others. I'm not sure what I have laying around but I think I have a few Crusader leftovers yet. Others who main Crusaders will likely have more stashed away. Playing in groups will help you acquire gems, mats, gold, and leftover items quicker.
I think you have a lot yet to go before throwing in the towel.
