Configure Wordpress Site

I have started a Wordpress website ([login to view URL]) but I require some help to configure page features and work with widgets and plugins. 1. Create a child theme and begin working from the child theme. 2. Remove “Leave a Reply” and “Post Comment” section from bottom of pages. 3. “Ideas” tab is to be a wiki page indexed to [login to view URL] “Ideas” page should look and act like a Wiki, with options for people to create and edit wikis and also to create a table of contents and include doc and pdf files. 4. “Training” page to include 3 sections: Upcoming (list of upcoming training events), Live (eventually integrate [login to view URL]), and Archives (Blog section with 3 Categories – Sr. Pastors, Youth Leaders, Children’s Ministry) 5. “Chat” page with landing page explanation: "This function of the Church Partner Website is usable to Facebook users. If you do not have a Facebook account, please subscribe and then return to this page” Once they return a link will take them to a closed Facebook group. Is it possible to stream the Facebook postings to this page? 6. “News” similar to Chat page but directed to Facebook page. 7. Members page. This can follow. The eventual plan is to have a subscription to the website that users pay and then get access to full website. It would require a Registration/Login landing page. Registrations would need to be transactions through multiple payment providers in various countries, but bring them back to the main website once payment is successfully received. (E.g. Paypal in Canada to a Canadian account, Paypal in USA to a US account, ePay in New Zealand to a NZ account, etc). I started to use the Userpro plugin, but not sure if it is the best option. I would also like the members to be able to post their profile and search for other members in their country or area. 8. Events page has been started with basic events calendar. 9. Ad widgets are planned to be added to the bottom area along with more sliders, but I can do this.
