CS3 Bridge - Batch Image Resize

i am new to using Bridge. I need to Batch resize images for my daughters yearbook. I need to resize pictures that are 36" x 27" and resolution of 72 dpi and change them to about 2" high but keep a high resolution (300 dpi) for printing. I tried to batch change them but they stayed at 72 dpi and became fuzzy.

Can you give me a tip to complete this process.

Thanks you
Molly
