However, I was not able to change the term 'Level Name' or 'Welcome Page' as displayed by this shortcode: [wp_eMember_my_membership_levels show_welcome_page="1"]
Right now, they are hard coded into the plugin. You'll find them in the eMember_auth_utils.php file, under the emember_my_membership_levels() function definition.
One other thing I would like to do if possible. When a member logs in I would like them redirected to their account page.
Is this what you are looking for?
