"New" button, need to make it larger(hard to click for some)

You'll need to add a rule of line-height: 15px!important;
to the other rules you've added. The height should match the height you specified (which is 15px) so that it centers vertically and the !important modifier is needed to override an important modifier specified elsewhere provided it is of the same or greater weight as the other important rule and follows it in document order.

I believe that that's going to do the trick!
