Yeah, it's really impossible to guide you on reputations since it depends entirely on how you plan to build your ship.
I know for me, the ones I use the most are Discovery for the Warp Core and Shield, Competitive for the Engines, and then some others like Gamma for things like the Ordnance Accelerator or Omega for the Assimilated Module.
You can level them all at the same time, I would recommend just do a couple randoms and pick different marks each time, then just do the 20hr daily on every rep that you have marks for. I usually just level them all, even if there is nothing in a rep that I currently need, I tend to change up my builds all the time so it's nice having access to anything I would need.
