static posts and widgets

Hello!

I have a few questions… I use the Spirit theme- my url is nicolebeholds.com. I would like for the home page to include static posts that I can choose and that will be listed at the bottom of the page. How do I do this?

Secondly- I would like a few widgets to include my personal instagram feed and another with my twitter feed. How do I do this? (I try and try but can’t do it despite all my plugins.. in the editor mode, all I see is “text” as a widget option and when I click it, nothing comes up)

Third- how do I insert more visual images on the homepage for social networking? You’ll notice the textbox with the f, for facebook and bird for twitter, but how can I find one and install it for instagram and pinterest and email/subscription?
