Spend some time looking over the documentation for both UITextField and UITextView. They both have a 'text' property that you use to both set and retrieve a text value. Ex:
Code:
NSString *stringToSave = [myTextField text];
[myTextField setText: loadedString];
How you save it and load it after that depends on what you need. If it is going to be a small amount of data, check out NSUserDefaults.
For the font stuff, again check out the aforementioned documentation. Also, poke around with those items in Interface Builder.
