Answer 1

"I wish I 'were' ready to go shopping at the mall" would be the correct form of the verb for this sentence. Hope we helped! :D

Answer 2

B. Were

"Were" is only appropriate after "I" when the sentence is in the subjunctive mood.

For example:
I wish I were a cat. I wish I were rich. I wish I were ready.
