Edited to add: I used your tips this evening with my science officer main going up against both Romulans and Klingons and they helped immensely! One thing I'd like to add, if I may: From what I've seen, each of the oppo races has their own fighting methods that reflects their culture. Klingons, Gorn, and Nausicaans will close to melee. Romulans and Cardassians (at least those few Cardies I've tangled with so far) prefer to stay at range. Orions will mix it and match--they'll both close with you and stay at range--they're the most flexible.
