sell the bridgestone pending it really doesn't fit you. I like a 54-55ish bike, and i'm 5'10". on my 56 trek my jewels are resting on the top tube, but i'm rarely standing over my bike. i have a little less than a fistfull of seat post (old steel geo, about right) so it's a bit big. if you're 5'7" then i don't think the 56 bridgestone would fit the best. (you know how to check if you're getting proper leg extension right? you want a slight bend in the knee to prevent damage. good approximation is when your heel is on the pedal and your leg is straight, then when you pedal with the ball of your foot you will have a good amount of knee bend)
looking at the questions you're asking i'm guessing you don't have a whole lot of bike experience, and thus not much experience maintaining and working on bikes. If that's true, I don't recommend buying online since you'll have to do work (though bikesdirect says just put the stem on, handlebars, and tighten wheels, they need a lot of work to be proper. wheels need to be trued, bb needs to be taken out and the threads greased, reinstall cog and lockring with grease and tighten. nothing super hard, but not things many people are comfortable doing on their own).
check around at various shops, see what's available. the globe i'm sure is fine, most people bash it because quality is comparable to a kilo tt, but it's more expensive. the globe comes with lbs service and a place to pose your questions to (and being new, there should be a lot). plus the shop will make sure your bike is in safe riding condition. if it isn't you have someone to blame.
specialized and trek are two big companies (I believe globe is actually a trek subdivision). so maybe take a look at the langster (i like that bike, but people don't like the look of the compact geo and aluminum ride). iro has some brick and mortar dealers, the mark v is nice for a beginner frame. the SE lager and masi coltello aren't bad either.
if you let us know what manufacturers are available at your local shop/s then you can get better suggestions as to what to get.
