Talking to myself, but I thought of another one:
Give your BOs Expose weapons, and use an Exploit weapon yourself. This is simplified, but basically there's no point in your whole team using expose weapons, or your whole team using exploit weapons. You need both.
Some others that may seem obvious, but totally aren't if you're just starting out:
Match your ship weapons to your captain's weapon skills. If you already have 9 training points in phasers, and none in tetryon weapons, try to find some good phaser weapons on the exchange.
The same goes for matching tactical consoles to ship's weapons. This is also kind of obvious, but there are consoles for weapon flavors (phaser, disruptor, tetryon), and weapon types (beam, cannon, torpedo). A pre-fire chamber won't help out a ship with all beam arrays and torpedoes.
You get a free respec at each major promotion, so don't be afraid to use it. Did you accidentally assign training points to mines, when you never equip mines? You can fix it by visiting the trainer at the center of ESD (among other places). You can also buy respec tokens in the C-Store.
When you're just starting out, get a tac BO with high yield torpedoes. This is totally a matter of opinion. When I first started in open-beta, I loved beam overload (even though it was bugged and your beams sometimes stopped working completely). Then I discovered high yield torps. Hit an average enemy with a tachyon beam from 10 km, fire your high yields, and then quickly broadside them with beams, and you can often take the ship out with just that first volley, even as a lowly Lt.
Here's one I read recently, but haven't really tried yet. Get your BOs to mount a frontal assault, while you sneak off to the side or back of the group for maximum flanking damage. You can do this by setting waypoints for your team. Also if you tell your team to attack first, they'll draw most of the aggro, leaving you free to flank. (Learn the team and team member commands available to you as icons by your team members in the upper left corner of the screen.)
Anyone else? Helpful hints for our newbie brothers and sisters?
