dude, you are getting too picky. and chances are, once you get into the sport, you'll want to upgrade your bike (somehow bike weenies love to stimulate the economy). and let's just get the basics out of the way.
-what's the total amount you have to spend. this will be for bike, pedals, shoes, helmet, and some decent cycling cloth (shorts with chamois becomes a necessity when you go >60 miles), bike pump, saddlebag, spare tubes, and a multitool. the above is the bare minimum for having safe, worry free ride (read, to get you home should you blow out a tire). also suggested are lubes (or your chain will wear out & drag down other parts as well), track pump, cycling computer, heart rate monitor, sunglasses (preferably with interchangeable lenses, as you'll kick up a lot of dust when riding, and the clear lenses are there to protect your eyes at night), and lights.
-where do you live? if you live in sunny socal, you just need a jersey, a pair of shorts (both washed often), arm warmers, knee warmers, and gloves (lifting gloves would do at the beginning). if you live in places with four seasons, pretty soon you'll find yourself needing booties (for winter), base layer, fleece, winter gloves, baclava, etc.
-are you good with tools? or at least, are you willing to learn? parts need adjustment, to say the least, and going to the bikeshop for small repairs gets expensive in a hurry.
case in point: my new bike and all the ensuing costs
bike: $2025 for a previously demo-ed C-dale six13 ultegra.
other stuff: $1200. that's for helmet, winter gear, components, and team kit
if i were you, i'd troll ebay & craigslist for a used bike, bring it to your LBS to get fitted. ride it for a year or so and see if you like the sport. many people give up the sport after 500 miles (that's about what i average in a month, many where easily do 2 to 3 times the amount). most good ebay deals are results of people giving up after a brief period. they think an expensive bike will make them faster but get discouraged when they get dropped by people on bikes costing a grand less.
