It's absolutely OK to turn off Cellular Data if you have a minuscule data plan or you don't need internet when you're not at home. When Cellular Data is off and you're not connected to Wi-Fi, you can only use your iPhone to make phone calls and send text messages (but not iMessages, which use data).
You do not have to switch it manually, although generally you need to choose the wifi network one time (and possible enter a password or go through other authentication) before the iPhone will use that specific wifi network automatically when it is available. Some apps create network traffic all the time.
