So I jump on the block as it reaches the belt, ride it for a moment and kill the one guy, then jump to the platform where the guy was standing and go up the ramps as far as I can (which is as far as I've gotten). Then once I reach that point, I need to jump on the block again and find access to the next highest set of ramps? Ok, I'll try that.
Thanks for the help. The Rogue Squadron forum was very helpful too.
