Develop & Customize Wordpress Theme (Advanced)

Hello there. I recently purchased the Glocal directory theme for wordpress and am having some issues that need fixing. First is the wordpress branding. I need to get rid of all the wordpress branding so my site is more secure from hackers and hide it if possible. Most links are showing as [login to view URL] and I don't want the wp to show anywheres on site, including links. Second issue I'm having is that on this directory it allows users to add events. In the events section its allowing all users to restrict administrators from viewing it, and I'm not sure why. Third issue is that I have an affiliate program plugin on the site, which allows members to become and affiliate, shows earnings and so on, but I don't see anywheres where they can add their payment info or request withdraw what so ever.. Sort of confusing. Another problem is with the shop. I added woocommerce so members could sell products and for some reason it doesn't show an option where to add their payment details again or withdraw money. One more problem, some account types and roles are interferring with others. Example, I have 3 packages, free, premium, platinum, but if someone signs up using the affiliate form rather than the login form than it makes their account some crazy kind of account that looks nothing like it should be.. Sorry I can't explain that better, but it's really odd and I'm not sure how to explain it. and last but not least, when emails are sent to users after they register, or any email that we send, it always shows as it is sent from wordpress. We don't want that either.. Can you help?
