App-selection is going to be trial-and-error, like on any other platform, to find the ones you like. A lot of the same apps available for iPhone/iPad are also available on Android. The Market also shows Comments from other people who have installed the app, so that's a good starting point for determining if you want to give something a try or not.

Note that when installing an app, you get a warning listing the types of data and every hardware and software capability that the app will have access to. If the single-player game you are installing is asking for access to your contacts list and the phone function, you may want to wonder why and cancel the installation.

A widget is something that sits on your screen and does something more than just act as a button to start the app. For example, the WeatherBug widget puts the current conditions at your location right on the screen. A calendar will put your upcoming events and reminders on the screen for you. They're kind of like Desktop Gadgets in Windows 7 and Vista. You can move widgets around and mix them in with app launcher shortcuts however you like.
