Problem with Logo & top bar

Hello,
For the life of me I can’t figure out several things with this theme and I really need someone’s help. A I’m trying to moving the grey bar up in the right hand corner, bring it down and center it and then set my logo on top of it. How can I change the font color of the titles of my pages? Or can I? Here’s the link to my page: https://www.longitgroup.com
Thanks for your help.

Sincerely,
Tommy Long
