A couple quick tips that are grossly over simplified:
Get lots of light on your subject. Colours (notably reds) start to fade in as little as 8-10 feet, so unless you are pretty much right on the surface, your pics will need to have that lost colour replaced.
Get close. Then get a little closer. There are 2 reasons for this. First, in most cases, you want the subject to take up a significant portion (most) of the image. Secondly, see my first point. If you are starting to lose the reds by 8 feet, that means that if you are 4 feet away from your subject you will start to lose the reds that are replaced by the strobe.
Shoot up. If you can't shoot up, then in a "worst case scenario" shoot level. By shooting down or towards a wall, your image will almost always appear flat and boring. Try to shoot upwards and if possible to isolate your subject whenever possible.
Shoot in RAW (if your camera supports it) and expect that you will have some work to do on every image in post production when you get home. (The better the image is when it is captured, the less work you will have to do in post production.)
Remember (and apply) the fundamentals of good composition. Things like the "rule of thirds", interesting subjects/boring backgrounds, some form of interaction all still apply.
