Customer Portal Customization Issues

Customer Portal Customization Issues

I'm having a couple issues trying to get my customer portal the way I want it to.

1. I'd like to remove or change the text in the top bar of the screen and I'm having a hard time finding how to do this. Right now it's saying my company name but my logo right next to that already says the company so it's really repetitive.

2. I'd like to add more clickable icons like in the "Customer Portal Essentials" section. How am I able to add these?
