well you first should consider whether you really want to design with Cyclone I. you might be better off with CII or CIII
next you'll need to choose a configuration scheme. active serial with an EPCS (or some kind of compatible SPI, search the forum) is the easiest option. you'll also need an oscillator and power supplies at a minimum
if you use CIII you can use Altera's schematic review worksheets and pin connection guidelines. even if you don't use CIII you can still get an idea of important things to check on your schematic:
