Maybe; you could have Palpatine exploit Anakin's lack of a biological father by saying that Plagueis created him, and that his destiny belonged to the dark side of the force all along, which could be a motive for becoming Darth Vader.

Or just never mention Plagueis at all, that wouldn't affect the story much.

This is a decent idea.

I feel like his name was just shoehorned into the film as it was. It didn't mean anything aside from basically giving Palpatine's position away.
