The purchase is actually made through Google Wallet, but you start by tapping the plus (+) sign next to where your piastres and money are displayed in the game window. From there it should bring up a choice between money and piastres. Then it shows a list of purchase amounts to select. Once you choose one, the display should transition to Google Wallet to complete the transaction to charge you mobile account or credit card.

As to "is it worth it?," that is a personal choice. You are spending real money on virtual resources. It helps speed the game up for many activities, but in this game you can also get most things done with some patience and some time. It's really your choice.
