Hi Janie,
The main site can be very intimidating, but there's some good stuff in Crossfit if you can get past the machismo of that first page. All of the WODs can be scaled and/or modified to any ability or age. Check out Mary Conover's article "A Crossfit Grandma", she started at age 69!

I started by doing some of the WODs that felt accessible to me - meaning that I could do them with little or no substitutions. Some of my first ones were things like Leg Day (
here), Cindy (with jumping pullups), and Helen (again with jumping pullups). I added in some of the harder ones as I got more comfortable with it.
A great place to start with Crossfit is at
Crossfit BrandX's forum. The mods post scaled versions of the WOD there everyday. They make it very, very accessible. The folks there are also very nice and willing to help out a newb.
Also, don't feel that you need to do the main site WODs. I was for a while, but have branched into WODs from other Crossfit affiliates and offshoots.
New Jersey Crossfit is great if you're into kettlebells at all,
Crossfit Kids is also has some fun stuff (don't be fooled by the "kids" part).
I'm currently doing stuff from
Gym Jones and
Mountain Athlete because they get more sport specific (skiing for me). I also frequently make up my own WODs. You can make the Crossfit ideology work for your goals.
Also, I wouldn't start out by doing all Crossfit all the time, especially 5 or 6 days in a row. I did that when I really started getting into it and burned myself out in about 6 weeks. The WODs are strong medicine, especially if you're approaching them with the intended intensity. I'm currently doing WODs or something like them 2-4 days per week in addition to other stuff (working on oly skills, heavy barbell work, cardio, etc).
I hope this helps.
