I think "I, ET" is the worst Farscape episode in the first three seasons, and quite possibly the worst in the entire series.
I would do the Pilot, PK Tech Girl (skippable--but it's solid and it's helpful to know who Gilina is for Nerve/Hidden Memory), DNA Mad Scientist, They've Got A Secret (if you need to explain Talyn and D'Argo backstory), Durka Returns, A Human Reaction, A Bug's Life, Nerve/Hidden Memory, Family Ties, and then as much of S3 as you've got and can fit in, really. Well, skip Revenging Angel. But aside from that.
I started watching with Fractures, then Sci-Fi had a two or three month hiatus during which they reran the entire series -- so I saw the end of the twin John arc, then went back to beginning. It worked.
