First off, congrats on the pull. You have been blessed by RNG.
You already have Pyromancer Bloodmage. You should cover every element first before getting more armors for an element, especially fire since there is an absolute abundance of great fire armors.
The best Bloodzerker armor to get is Terra Bloodzerker, as there are very few good earth armors, and it is by far the best armor of that element.
The general recommended priority of UR GGBs is pet & guest (which you have for your main), armors, weapons, and everything else. However, there are certain items that are so universally useful that one should get them regardless of this order. One such item is Prime Chaos Orb. It will substantially increase your damage output for nukes.
I wouldn't recommend getting anything for an Adventurer when your main account still hasn't completed his equipment. However, Dunamis is the best thing for a warrior, and rangers are probably better off becoming beastmasters and getting an elemental variant Bard of War when it comes back.
