(Easy?) Fixes to Tumblr Theme - HELP! Options

[JoeyRamon]

Hey there,

I'm putting the finishing touches on my Tumblr-based website at http://ethanfixell.com, and can't seem to figure out how to make the following minor adjustments:

1) Increase spacing between text paragraphs

2) Extend the background for permalink pages (e.g. the background stops abruptly on http://ethanfixell.com/about)

3) Decrease the spacing of the "tweet/like/share" buttons on each permalink page (they are further from the text than on the index page)

I've attached the HTML coding to this message. If anyone could help me with these small changes i would GREATLY appreciate it!

Thanks so much,

-Ethan
