Take the beginners MSF.
Sounds like operator error on the shifting. It's not the smoothest but for the price of bike you get what you pay for and its not really that bad.
I also don't feel the mirrors are bad either. There is a whole thread about them in this forum. You can buy a spacer that pushes the mirror slightly out further. It helps to see more without having to more your elbows so much.
Good luck!
