Answer 1

The structure CSS is used to make a completely custom theme, where you do not want to rely on any of the default themes that come with jQuery Mobile. It's a very basic bare bones stylesheet. You can use it in place of the main jQuery Mobile stylesheet, then you create your own stylesheet to override and customize.

Answer 2

Personally I seperate the structure css out so I can make changes to my themes without causing any major issues to the new theme.css architecture. Makes it a bit easier to make upgrades as new versions come out. Though it is a little tricky to verify that there are no new additions to the themes. I wouldn't use overrides on the base themes a,b,c,d, - I find it's better to build your own themes using those as bases, e,f,g, etc...
