Lily's eyes...a big mystery for ages. As far as Lily being related to Slytherin is concerned, I have to disappoint you. It's been a much discussed theory that came up two or so years ago, but JKR shot it down in a interview saying that Voldemort is definitely the last remaining descendent of Salazar Slytherin. So, unless you can think of a way that makes Lily related to Slytherin but not Harry, that rules your theory out. The interview is somewhere in the HP lexicon, it should be among JKR's comments on Lily or Voldemort.
However, that doesn't solve the question why Lily's (and Harry's) green eyes are so very important for the story. I, too, wonder if the colour itself is of significance. Slytherin liked green (apparently)...Voldemort likes green (most certainly because Slytherin did...oh, the peer pressure)...snakes are often portrayed as green...The Unforgivable Curses are the only curses with green light...basically, green is evil. Hm...
