I don't know how many pins a current Cortex A-9 has but I'd bet it's over 300...
Varies depending on the precise implementation. The smallest I'm aware of is the Allwinner A13, which has a 176-pin package. It's possible that some application-specific chips have fewer: the A13 is designed to run with external RAM and NAND flash, high colour LCD display and multiple additional external peripherals, which explains the pin count -- but if you designed a chip with onboard RAM and storage for an application where monochrome display was standard and you only wanted to talk to a handful of peripherals, I'm sure you could get the pin count down to something a lot more manageable.
