Corrected entry: Why doesn't Mary Jane know that Spiderman is Peter Parker? He speaks to her on a number of occasions and even though he's in full costume, his voice is clear as a bell - he doesn't disguise it at all. She'd recognise it from a mile off.

Correction: The same way that no one realized Clark Kent was Superman with glasses. It's part of the suspension of disbelief involved with comics and comic book movies.
