Atomizer = that part that vaporizes the liquid, made up of a coil where the electrodes are connected to the battery by the threads and center piece where you screw it into the battery (aka 'batt') and an 'atomizer bridge' which is the raised area when you look down the tube of the atomizer casing. The bridge has a fiber material (don't pull on that) and a metal mesh and sometimes metal mesh at the base that absorbs fluid.
Atty - short for atomizer
510 kits come in various configurations - here's a few:

'Starter kit' - 2 batts, 2 attys, 5 carts, charger (basically two ecigarettes)

Joye 510 with PCC
Starter kit with PCC - same as starter kit above but with a PCC (personal charging case) which is a case that can hold some carts and a cart and an atty, and a place to charge the ecig battery. The case has an internal battery that you first charge via a mini usb port for 4 hours. You can then disconnect it and travel with it. YOu can do about 5 charges of your ecig batt while 'on the go'. IOW, it will likely last you from 8-12 hours depending on how much use.

Cignot has sold out of the PCC kit, it appears.
Starter kit with Passthrough - starter kit with a corded device that plugs into a usb port and has an inline battery and a 510 battery casing where you screw in the atty and cart. This way no battery charging needed but you're tethered to it so good for at the computer, watching tv, in the car (usb wall and car plugs available)

Some vendors add other stuff, juice, extra attys, etc. That should give you an idea.
