Don't use the Plasma Pistol. Go beat campaign for the Alien Pistol - should do you some good. Along with that, get her the Fast Death and have her upgrade it as much as possible.

Now, in terms of playstyle, it's a good idea to basically walk large circles around the map and shoot any foe you see - aim for the head, it's rather easy to hit and increases your damage. Along with that, circling your opponents is a decent trick, and reload between kills (if you're not under attack!). Learn how each weapon you use works, and try to use that to your advantage.
