Locations/Steps for changes

I'd like to make 3 changes to Scholar, but need to know where things are located and any steps required to make the changes.

1. I want to leave the slider and all other features in place but want to move the sidebar from the left to the right. Where can I do it and what steps are needed to float it?

2. I want to remove the space where the title normally goes (below admin/search, above menu).

3. Also, is there a way to suppress the space underneath the menu where details about the menu option go? Where and how do I change this?

I'm trying to streamline the header so it does not take up so much real estate at the top. Any help appreciated. Thank you.
