Fix issues in my site WordPress

Hi, I need to fix the issues on my site: - Insert in the same template that I have now to change / restore password. (currently done from wordpress / default, I do not like is) - In a section of the site not all posts are, only the last, I would like everyone to see. - De-index posts are visible for registered users. - Add a text editor, you can add bold, change text size, color .. etc. (for now you can not do this kind of details, only supports plain text with no more). - Can edit posts (now you can not, it seems to give on the edit button not load all the page) - Change the logo of the newsletter (now default, plugin: MyMail of Codecanyon) That's all.
