System repair is good to have if you already have drones. The helm upgrade actually should have been priority #1! It's not for the effect but the damage buffer. If helm is at level 2 your evasion doesn't immediately go to zero when helm takes 1 damage. The compound effect of piloting being knocked out can be absolutely devastating and I'd suggest it as the very first thing you spend scrap on. Strictly because it let's helm take an extra hit before being totally disabled. The same applies to a few systems though I'd make it less a priority. A level 2 med bay or o2 room doesn't ever need to be powered to level 2, but the empty power slot ensures the system will run after a hit, I'd especially consider doing this for weapons and if you have dome extra scrap near end game and are okay working with 3 shields, that power slot that doesn't amount to a full shield still means you keep your shield at full even if it's hit once instead of losing layer if one laser shot gets through.
