You have an excellent start there. I would recommend these additions, eventually:

Ditch the Iceburst brandish and get the Avenger line; the charge attack on Divine Avenger is great (also, highly recommended for FSC)
Start the Calibur line and get a low or med CTR if you can (the 360 sweep charge attack is great, and Calibur is a fantastic general purpose sword)
Nightblade is good, develop it into an Acheron if you want some serious slime/gremlin-killing power, otherwise the Calibur will serve you just fine

Your choice in shield lines are both good, I would add the Blackened Crest/Crest of Almire once you are able to.

I personally prefer a Voltech, but any status alchemer is serviceable. Silversix line would be a useful add, but is not necessary in any way.

Since you are primarily swords, I'd recommend a Shivermist for some crowd control. Keep in mind the bomb radius only starts getting useful at 4* though.

As for armor, wolver gear is fine- there's a reason everyone uses it. You can mix and match Vog and Skolver in the end for elemental/piercing defense. I usually invest more into weapons and rely on skill to stay alive (this is not a game where you can tank hits, even with maxed defenses versus whatever you're facing), so I just gear for the most troublesome damage types (ranged elemental; shadow from fiends is a close second).
