Changes to text / padding area on pages

Hi,

I want to make some changes to
1) the spacing between lines (reduce if possible make them bit closer)
2) increase padding left and right of page so that its similar to this screenshot - http://monosnap.com/image/1nHdMNV512VOKPAwNYVWy49dKW6onz

applied to this page - *URL(S) REMOVED*

if possible also applied to these pages
- *URL(S) REMOVED*
- *URL(S) REMOVED*

Thanks

Tom
