Install AVRStudio if you haven't done so already, it has a simulator which you can use with break points to determine the exact delay you're getting. You'll never actually get 1mips per mhz from an AVR because branch instructions take between 1 and 3 instructions to execute (and the execution time depends on the data) Your parts have enough memory, I'd give C a shot, as long as you tell the compiler your processor speed it has a calibrated delay loop already.
