With the base model of the iPad 2, you get WiFi connectivity and 16GB of memory; the next model up, with 32GB, will retail for around $100 more; the next higher model, with 64GB, will cost yet another $100. There's another class of iPad 2, however, with both WiFi and 3G connectivity. This series starts at $629, again with more memory increasing the price by $100 each time. You'll want the WiFi + 3G model if you wish to connect the device to information sources both at home and while on the road.
