Oooh, a potential new 'Phile! That's always exciting!
Looking over the episode titles, the ones that jump out at me would be -
Season 1 - Pilot, Squeeze, Ice, Beyond the Sea, Tooms. Yes, there's not much mytharc there but the S1 mytharc didn't set up much other than Mulder's belief in aliens and these eps set up the growing relationship between M/S pretty nicely, IMO.
Season 2 - Duane Barry/Ascension/One Breath, Irresistible, Colony/End Game, Humbug, Anasazi. Some good background mytharc eps here.
Season 3 - Blessing Way/Paper Clip, CBFR, Oubliette, Nisei/731, Revelations, WotC, Syzygy, Grotesque, Piper Maru/Apocrypha, Pusher, Quagmire, Wetwired, Talitha Cumi. To be honest, I don't remember exactly what is in all the mytharc eps this season but I'm sure they're important LOL. This is the season the MotW eps started to really, really be good IMO.
Season 4 and beyond (at least up until Season 8/9) it gets a little harder for me to find eps that can be skipped. Most of the MotWs are worth watching for the little bits of M/S goodness, and the mytharc eps were fairly interesting as well.
So....good luck. Heh.
