While I wait for yet another gel to finish running, I may as well put in my two cents on Maya and Ritsuko (note the AND, not x).
From the EVA I have seen (all 26 eps and Death/Rebirth, have yet to see EoE), I never noticed Maya having anything other than enormous respect for her mentor. Perhaps idol worship, and that's about it. Considering how brilliant, talented, and dedicated Ritsuko is, Maya's admiration is quite reasonable. I wouldn't be surprised if Maya had a crush on her. I don't think Ritsuko would ever return it though.
For some reason, many people I know didn't like Ritsuko at all. Some found her utterly despicable, or pathetic, or couldn't scrounge up any sympathy for her. I saw her as possibly the most well-off of the disfunctional NERV staff. Misato is an incredibly competent tactician, but she IS a flake and an alcoholic. Ritsuko didn't seem to have any major issues until towards the end, when stuff about Gendo and her mother are revealed. I didn't find her pathetic for continuing her mother's work - she wouldn't have been able to maintain that position if she wasn't skilled at it.
As for Maya, I didn't think anything of her when I first watched the series. I noticed her during my second viewing. I thought, "Hey, she's the underappreciated lab tech who's always there!" She may be much more timid than Ritsuko or Misato, but she does have competence. She's a peripheral character, and never undergoes any development, and she remains under Ritsuko's shadow. However, she does stick in my mind wheras the other two lab techs don't. All I remember is that one guy has a crush on Misato.
