Put rank points into tactical officers and engineers for the first 20 levels or so. Having a lot of decks while you're under rank 40 will kill you. Research hull first and foremost. Rely on Dominion Cannon Mk 1's for your weapons. Don't bother with defenses until you get higher in rank.
Wait until your research gets going, THEN all rank points should go into decks.
Here's what I have. (I just reset)


2 deaths came from omicron mine traps. (I have a subspace seeker, just haven't bothered to go on a scan run yet)

My recommendation for research if you're just starting out
1. Hull
2. Scanners
3. Planetary Bulidings
Join a big legion that can give you some traps and Kurenite.
