I made a Suggested build to start the Arbiter.

• Front Weapons: My Favorite would be Advanced Fleet Beam Array [CtrtH][Dmg]x3 - currently I show just one: I sent you a bunch of free Beam Arrays and Dual Beam Banks. Test and see how you fare best in mixing. Buy Fleet weapons when you have got the Fleet ship and the 2nd Science console.
  
• Nukara Deflector and Engine: an Energy saver Combination gives extra weapon damage
  
• Iconian Warp Core: a good one.
  
• Maco Resilient Shields: Energy Collector
  
• Aft Weapons: Sphere of Influence mission, Omega Reputation, Crafting
  Devices: maybe Catalyst out, Temporal Negotiaor in
  
• Engineering Consoles: 1*Crafting, 3*Reputation
  
• The Science Console: buy at Mk X, upgrade to Mk XII
  
• The Vulnerability Locators: Lifetime investment.
  

See suggested Traits and on Duty Officers see Notes. The Replicator helps on Engineering DOff Tier 3 & 4 to get 2 of the Damage Control Engineers for a reaonable price.
Bridge Officer Skills: should be easy to get except Reverse Shield Polarity 3.

This is not a final build, this is how I would start, assuming Tier 5 Reputation everywhere.

This is how I would grow:
Upgrade the Science Console to Mk XII first. Master the Zen ship, get the Fleet Ship and master it, with a 2nd Sci Console Mk X -> Mk XII same type. Get the free front beams replaced by Advanced Fleet [CtrtH][Dmg]x3 weapons.

Long term goal should be to get everything to Mk XIV. What to do on the Space Engine Set... first find what needs to be changed, and if the next big space set gets a better reputation than the Iconian set. The current combination is just a bit of an energy helper, and does not cost Fleet Credits. 3 Delta Pieces and the right energy caring Fleet Warp Core (see spire and mine) can be better.

Also: keybindings help a lot! The Forum has some posts on this.
