Small coding changes to Wordpress theme

I've installed a WordPress theme that needs
1. Some small adjustments, mainly turning off some features and changing aspects of navigation, done through php and css editors.
2. Adapting some of the forms used (woocommerce and buddypress) in the theme.

I'm barely using any of the features of the theme, so the changes are simple. I've looked online and there are generally instructions for the things I want done on forums. An example of changes attached.

I'm looking for someone who can give me good ideas of how stuff should be done too.

I need the work to be done very soon.
