Question: If Bella is a "shield" and vampire powers can't affect her how did Jasper use his mood/mind control on her? It was Bella's birthday and they were at the school. Alice was inviting her to a party. After Bella says yes, she said "Jasper, no fair with the mind control thing."

Answer: Vampire abilities can't affect her mind. It's explained in the book that what Jasper does is physical. He loosens tense muscles and stimulates production of the appropriate hormones and helps the subject physically relax, thus stimulating a sympathetic mood change in his subjects.
