Had a chance to stop by K & S photo in Palo Alto, CA. They are a high end photo store with an entire lighting department (we don't have these type of stores here in maine). He recommended this Elinchrom 2-strobe system with D-Lites. He also recommended strobes for portraits, as long as it wasn't children. For children he found with continuous light sources were better. I also didn't realize that this type of system doesn't have a power pack of some sort. The stobes plug into the wall and it was about $800. For a system with a battery to take you there was a significant uplift in price to ~ $2000 - $2500!.
K & S is a great place.
I think strobes are fine for everyone except babies. There are people that believe you should not use flash with babies. Clearly flash through a big soft box is not as bad as on camera flash directed at the baby. I'm not sure if there is any real evidence one way or the other concerning the effect of flash/strobes on babies, but if you are planning to photograph babies, you should think about continuous lights.
Many indoor locations have inconsistent types of lighting, mixtures of tungsten, florescent and sunlight coming in through windows, perhaps colored windows. This light does not mix will with your strobe or continuous lights. You will end up with different white balance in different parts of the picture, which is almost impossible to correct.
When possible you want to overpower the ambient light with your strobes, not only on the subject, but also on the background. Sometimes this just isn't possible (like taking pictures in a big church), but for studio style portraits it should be possible to light the subject and the background with your lights.
You can do that with continuous lights too, but you basically need a windowless studio where you have complete control over the ambient light. Otherwise your lights will be so bright that the subject will be squinting. You could also try closing curtains and turning off many of the lights, but that is not practical for lots of location shoots. You may be able to do that though when shooting babies.
Two lights is a start, but you will quickly want hair lights and background lights too.
I believe that some people have been able to use the Paul Buff Vagabond Mini portable batter power pack with other brands of strobes. It is only $240.

He also talked to me about umbrellas vs. soft boxes but I need more help understanding what is better or how the differ.
Shoot through umbrellas and large soft boxes both give very soft light with soft edges to any shadows. The main difference is the soft box is more directional with its light, where the umbrella spreads the light over a wider arc. You will get more light reflected off other things in the room falling on the subject. If the things it is reflecting off of is not white, it may add an unwanted color cast to your picture. For this reason most photographers use soft boxes in the studio and indoors. It gives them more control of where the light is going. Outdoors, where reflections are not as big a problem, I frequently use shoot through umbrellas, because they are easier to set up and tear down quickly.

So I learned that I should think about how many Watt-Second a system puts out. Maybe 200 WS is appropriate? Also he showed me a system with an additional "Hair" light.
You can certainly work indoors with a 200 w/s system. You could add more powerful strobes later and use the 200 w/s for background, kicker or some other usage. I'm not sure a 200 w/s is enough in some really bright sunlight situations where you need to light a large group, but you need to start some where with a budget you can afford.
As some others have pointed out, strobes range in price from very inexpensive to extremely expensive. The mounting system for soft boxes, reflectors and grids are not usually compatible between different brands. This means only certain kinds of soft boxes will work on a given strobe. If you decide to change strobes brands later, you may have to replace some or all of your lighting modifiers. Before buying strobes you need to look at the selection, quality and price of modifiers available too.
That said, Elinchrom seems to have good quality strobes and a nice selection of modifiers at prices that are not too outrageous.
