Thanks for reaching out to the Community with your questions. Being able to change the color of hyperlinked text is definitely something you can do. In fact here is a helpful FAQ we have on how to edit a link in a campaign email.
As for the bottom verbiage you would like to make edits to, what verbiage is it exactly? Is it the text in the footer of your email, where your business address is? Or is a different part of your email? Knowing the exact part you're looking to make changes in will help us know if these changes are possible.
