rows vs pullups

best for overall back development, concentrate on rows or pullups? For example, if you did say, barbell rows, v-bar cable rows, pull ups and chinups for back and wanted to add deadlifts in there but had to remove one of the above, would you subtract a row exercise or a pullup exercise?

Also, should you be doing the same number of sets of rows as you do for chest presses to "balance" things out, or is there no corrolation?

Take out whichever benefits you less, or alternate the removal of one of them from one workout to the next.

I would, if you had too, remove the cable rows.

BOW's + Pull Ups + Deadlifts =
