Your understanding is essentially correct. For a little further reading I'll point you at
application note: an-458-2.2 (
http://www.altera.com/literature/an/an458.pdf) which discusses all manner of using FLASH and more. Have a look at the "
implementing the advanced boot copier example" section from page 12, which talks you through lots of options and guides you through programming.
As for pin selection - you're pretty free to choose what you like, subject to ensuring you connect to (one or more) FPGA I/O banks operating at an appropriate voltage for your chosen FLASH device. My only recommendation is, having chosen a pin out, you run it through Quartus as a sanity check. I'd recommend this regardless of what you're connecting up to an FPGA. Always put a basic design together and run it through the tools.
