1. Yes, when a LOW level is applied to the OE pin, with OEPOL = 0 (default), all the I/Os configured as outputs are enabled and the logic value programmed in their respective OP registers is applied to the pins.
2. Yes, the INT pin can be left open (unconnected) when using port pins as outputs only.
3. I assume you need to take into consideration following timing parameters:
