Looks like most of your doubts are cleared but let me pitch in with my 2 cents.
Firstly don't go for sony NEX. Not worth the money; they have 2 lenses, a wide and a normal one, and the lens movement is very slow, It feels like there is little grease between the external and internal zoom/focus tube. Not desirable for prolonged use.
Secondly, ultra basic DSLR are canon 1100D and nikon D3100; after that you want little more extra stuff then go for 550D or D5100(These bodies are bigger than the previously mentioned 1100 and D3100 so if you're someone with small hands then choose wisely, ideally most of the camera controls should be reachable with your right hand without removing your camera from your eye.Take this into account when buying)
READ,READ,READ and learn before you buy one. If you don't know much about the do's;learn DON'Ts before buying.I've known people who have damaged their lenses accidentally by moving the focus ring in AF mode on a non-FTM lens(In canon). I have also known people who want to rotate every other ring on a DSLR coz they saw it in movies without even asking the owner. I have had a very bad experience with someone who was trying to rotate the focus ring on my 50mm prime in AF mode and at the same time asking me, why it is not zooming.!!!!
Always buy camera and other fragile stuff from a physical store, camera is a delicate equipment and you should buy it after checking it.(My personal opinion.)
You have not mentioned the city you're from, If you're from Bangalore by any chance then register
here and check out the camera bodies for a day(Be careful though since you're a newbie).
Another tactic used by many is to invest in a medium feature camera body and save money for lenses, it's the lenses that counts. Finally, It's the camera holder that takes the photos and not the camera itself.
