In the past this repository held all of the Raspberry Pi related Python code that Adafruit published. For example code to talk to sensors like the BMP085, TCS34725, and other hardware like character LCD plates. Over time we found it difficult to manage so much code in a single repository, and.
  6. IO Expander PCF8574 with Raspberry Pi With the Raspberry Pi, you can easily run out of IO pins. A good way to solve that problem is to use an IO expander to give your Pi a couple more IO. On Tayda Electronics website, you have two different chips, the 8-bits PCF8574 and the 16-bits MCP23017 from Microchip. These two devices can communicate with the PI using the I2C protocol, it only uses two.

In answer to your third question it looks like the TPL7407L is a pin compatible version of the ULN2003 with MOSFET drivers and negligible input current - it could be driven directly from the PCF8575 without pull-ups. As commented by Peter there is a 1 Megohm pull-down on the inputs but the PCF8575 has a 100uA pull-up so it should drive it ok.
