I want to do simple 3-point portrait lighting and I will use a light meter to set the camera based on the lighting I choose, however, being new to lighting, I do not know how to set the strobes.
I'm using the strobe with the softbox as my key light, and will use either the other strobe as a fill, or a piece of white board as the fill on a C-stand.
That's a good approach, but skip the second fill light for the moment, and just try a bounce card first. Many photographers use a sheet of Foamcore, Gatorboard, B-board (Styrofoam), foldable reflector, or white show card (tag board) for subtle fill. Since the reflectance is relatively low, you'll only see its effect if placed very close to your subject.

I am using wired synch, and I am currently in test mode (not sure if I should be in this mode), and I am not clear on what settings I should make to the strobe acting as the key. Can someone please get me started? What do I base the setting on the strobe to? Is this simply the intensity setting and you just have to cycle through all of them in trial and error, or is there another way of doing this?
I assume you're using a digital camera, so trial-and-error is fine. Since the Hensel Integra is a 500Ws light with a six-stop power range, I would start at its lowest power setting (1/32nd), which results at an output of 15.6Ws. At a base ISO of ISO 100, with the source 4' from subject, you should end up with something around f/4.0-f/5.6 (shooting through a double-baffled, medium-sized softbox). If your camera only goes as low as ISO 200, you should end up somewhere between f/5.6-f/8.0 at a distance of four feet (in general, studio portraiture is typically shot at between f/5.6 and f/11).
Positioning your key:
1. Set up your primary key about two feet above the subject's eyeline.
2. Start with the key centered (a lot of beauty photography employs a centered key).
3. If some shadow is desired, try moving the key off-axis a bit, but don't exceed anything more than about 30-degrees.
Basic light quality rules:
1. The closer the source is to your subject, the more "wrap." The more wrap, the "softer" the light.
2. The closer the source is to your subject, the more rapid the light fall-off.
Light fall-off isn't necessarily a bad thing, and for many applications, it's a highly desired effect. Light fall-off helps to create shape and form. I think most of those starting out in portraiture tend to light too "flat," with too much fill. A little drama is always nice; however, be careful not to move your key too far off-axis (which would create too much shadow). Again, the larger the source (relative to the subject), the greater the wrap, and hence, the "softer" the light appears. My preference is to place my primary key as close as possible to my subject (to maximize wrap, while increasing fall-off), while still being able to frame-out the softbox. Good luck!
