Raspberry Pi MCP23017 Port Expander Board Kit | RPI-PORTEXP | HobbyTronics link for Raspberry Pi MCP23017 Port Expander Board Kit.
These basically discuss how to extend no. of gpio of pins but it is up to you to decide how to use them and configure the accessory attached to gpio pins(here PIface i think).

Check this link for connecting a ultrasonic sensor and I dont think there is any option other than gpio pin extension.
well but you could use external usb sound card in place of wolfson.And then use gpio pins for anything you want to do.
