Nokia maps, wi-fi and sports tracker help on e71! - wi sporting clays

I have a Nokia E71 and wanted to know 3 things:

1) Wi-Fi is also known as WiFi, and if it cost money?
2) Is Nokia Sports Tracker does not matter if you?
3) in the Nokia Maps (GPS), you must buy round-by-turn guidance (guidance or not), it is loaded? When you buy, where to buy and how. When preloaded How do you work?

Thank you for your help.
