bring in some guides for the size that you want.. then use the transform tool (control T) then while holding shift.. you can reduce or enlage the pic proportionally.
then you can either use the rectangular marquee or the crop tool to crop the image.
marquee
select the area, then go to Image > crop
or if you use the marquee tool, just select area and double click in there.
you're a day late and a dollar short
