Should I use _ before private methods or just for private properties?

Use _ before all private member names. This includes properties and methods.

Should I use methodName or method_name for methods?

Use camel case (that means methodName).

Should I use "public $fooBar" or "public $foo_bar" ?

Separate words with underscores (that means $foo_bar).

Some of these are mentioned in the Class Variables and Methods section of the PEAR naming conventions document.
