R isomers are for pirates.
Basically.

Look at alpha position - there are two hydrogen atoms attached to that carbon atom, identical. The same goes for beta position. E.g. there are 4 different isomers of ephedrine because it has a substituent both on alpha and beta. A molecule needs 3 different substituents on some carbon to be chiral. This drawing style adopted means 1) no carbons marked and 2) if somewhere there's no substituent that's normally drawn there are hydrogen atoms so a carbon atom has its 4 valence (like in all organic compounds).

Your diagram needs 2 methoxy groups.

For 2C-I yes. The image isn't meant to show 2C-I but lack of chiral centers.
