The cat stump grinder will throw some chips, is easy to use, and telescopes as well as swings in a wide arc. I owned one and like it a lot.
I'd haul off any long, round logs larger than 7"-8" or hire someone to cut them to lengths shorter than your cutting width to facilitate chewing them up. Get some Cobra teeth in the middle of your drum, too, and you should have no problems on a job like that aside from occasional longer logs which will get kicked out under your machine necessitating backing up a lot to chase them.
Looks like a fun job.
