Religion class grades are not considered for UC admissions. If you took a year of Art then you should be fine in fulfilling the UC VPA requirement.
I would just report your quarter grades and if you feel it is necessary, your final exam grades in the additional information section as you noted earlier.
Were you able to calculate your UC GPA using the calculator link with quarter grades? Also as an OOS applicant, only AP/IB and DE course grades count for the extra honors points in the calculation for 10-11th.
