The wireless router will have to support AirPrint to be able to print from the iPad natively. If the router does not - few do - you'll need a third-party printing app such as PrintCentral.

No. Printing directly from the Mail or Notes app (or any other of the bundled apps) work only through AirPrint, so you would need a printer or router that supports AirPrint.

"The xPrintServer-Network Edition is a 'plug-and-print' hardware print server for printing from Apple iOS devices running iOS version 4.2 or higher. The device is roughly the size of an iPhone and uses the iOS native print menu. It requires no additional applications, software downloads, or printer driver installations and automatically discovers available networked printers supporting JetDirect / AppSocket, LPD and IPP protocols."
