I'm making a CD of senior pictures that I took of my friend, and I was wondering what I should set the resolution to and if I should resize the images in Lightroom? I'm still a little confused on the image sizing section of the export dialog in general. I think the photos will mainly be used for screen purposes; if she does make prints they won't be super large. Any help would be great.

Until an image is going to be printed, the Image Sizing resolution (ppi) is meaningless.
So for electronic screen display the Image Sizing resolution can be any number.
The Image Sizing resolution and the image pixel dimensions determine print size.
For example, a photo that is 3000 x 2000 pixels that has a Image Sizing resolution set to 300 ppi will be a print that is 10 inches x 6.67 inches. 3000px / 300 ppi = 10 inches. 2000px / 300 ppi = 6.67 inches
The same 3000 x 2000 photo that has a Image Sizing resolution set to 400 ppi will be a print that is 7.5 inches x 5 inches. 3000px / 400 ppi = 7.5 inches. 2000px / 400 ppi = 5 inches
pixels / ppi = inches
inches x ppi = pixels
pixels / inches = ppi
The Image Sizing resolution can be changed with just about any image editing application, and most online labs do that for their customers until the lab's minimum resolution is reached (usually about 100 ppi).
When the size of the ordered print falls below the lab's minimum resolution, the lab will refuse to make the print, usually with a notice the photo has insufficient pixel resolution.
