assistance assembling multiple WP_Query loops

URL: Fertility & Midwifery Care Center

Plugins Enabled: Only BuddyPress, latest version.

Problem:

I need some assistance with building multiple loops with WP_Query for the home page.

Details: As you can see from the website home page I would like to break up each section into pages, and then call them from the multiple WP_Query’s, but I’m not entirely sure how to call each page, then add a plugin, followed by listing a couple categories, and the list some of the authors (in this case, the authors are actually the doctors).

Page Layout (Here’s how I imagine I would call each section, starting after the big slider at the top of the page)

Welcome – get_pages
About Us – get_pages
Testimonials – Plugin
Services – get_pages
Our Team – list_authors
Twitter – Jetpack plugin
Portfolio – get_category: portfolio / sort: latest
Blog – get_category: blog / sort: latest
Newsletter – mailchimp plugin
Contact – get_pages w/ contact-form-7 plugin

Qualifications: I have been creating simple wordpress themes for a few months now and I am trying to get into some more intermediate/advanced “looping”. So I do understand the basics and simple WP theme development, but WP PHP is still new for me.

Thank you in advance for your time. 🙂
