More questions on J&E Plugin

Hey guys, great job on the J&E plugin so far. However, I have some questions about some stuff. Hope someone can enlighten me.

1) Is there a way to rename "Experts" to something else like "Professionals" sitewide? (see attached 1.jpg)

2) Some of my text are being cut off on the Add Jobs page and inbox page (see attached 2.jpg & 3.jpg). Is there any way to resolve this?

3) Is there any way to introduce a gap between the "Edit" and "Delete" button on "My Profile" page? (see attached 4.jpg)

4) The box surrounding the content on "My Profile" page is missing the top and sides (see attached 4.jpg). Is there any way to restore it?

Many thanks in advance!
