Hi Andrew
Get the Tiny85 chips as there's more RAM & EPROM to run your other programs... and probably don't cost too much more than the Tiny45, and are otherwise the same. The DIP8 is still fairly small and good to start off with. About the Fuses... not too tricky to but depends on your programmer software. I am familiar with Bascom-AVR Demo can be downloaded from http://www.mcselec.com which has easily selectable fuse options from drop-down lists. For this application you need to enable the PLL clock source, and disable the "Clock Division by 8". These are not the default options programmed into the chips as shipped.
