Morgana is probably one of the most complex characters in Merlin as from series 1 to 4 she changes dramatically. She has always done what she felt was right (even if it isn't the right thing to do). Morgana ends up being an evil sorceress because she was influenced by an evil sorceress.In series  3 I think the evil smirking was not necessary but I found it hilarious. It was Merlin and Morgana's way of communication. I believe that if Merlin had told her that he was magical and helped she would be in a completely different situation then she is now. I agree with you with why she would hate Merlin. She would also hate Merlin for trying to poison her. I felt so sorry for Morgana in The Fires of Idirsholas as she did not know what was going on and why Merlin would try to poison her or leave her at the mercy of the Medhir Knights.

Her quarrel with Arthur reminds me of a sibling relationship where one sibling wants what the other sibling has got. Except of course it has gone to the extreme of Morgana trying to kill her brother. I think that Morgana thinks that Arthur will turn out to be as bad as Uther and will not cease persecuting people with magic.

Defiantly all it is pure jealousy with Gwen.

I completely agree with you why she would hate Gaius.

I am glad that someone shares my views on Morgana not being a insane sorceress that tries to murder everyone.
