Jamie, the similiarities just don't end for us!

Yes, my birthday is also Aug. 18th! I turned 25 this year. It's amazing how many little commonalities we have!
As far as # of workouts per week, I have to say I usually do 6-7, but have done as few as 4/wk. during a few hectic weeks. Keeping up with my workouts makes me feel so much better in so many ways, so it's really become a priority. I do weights 3x's a week (M-W-F, usually, sometimes Sat. instead of the Fri.), and I think it's helped me to keep/gain muscle as I lose fat. I only spend about 25 min. doing the whole thing each time, so it's not a huge time commitment. All I do is about 5-6 upper body exercises (bicep curls, bench w/ just the bar, shoulders, chest flies, triceps, and lats), and then abs, and then leg press (I do my calf raises on it as well), and inner/outer thigh machine. That's all I do! I do 2 sets of 12-15 reps for each exercise. I do the 2 sets right in a row, with maybe a 30-sec. break between the 2 sets. I think all that helps me be faster! I'm not interested in building a ton of muscle, but I'd like a little, for tone, and I sure don't want to lose what muscle I already have, as I lose weight.
Hope that all makes sense.
On the days I weightlift, I also do the elliptical, so those are my most time-consuming days. Other days I usually spend between 30-50 min. on some form of cardio.
Well I think I've expounded plenty on my exercise routine!

Hope that helps.
Jen
