I was going to suggest changing the parchment background to a similar color. I think it looks better now.
To give the title some padding, go to the section with the variable definitions (I think that's what it's called, not 100% sure) and look for this:
#header h1
That's the blog title. Try tinkering with the margin and padding values. I'm not sure what your default values are, or whether even more than one is given....but if you want to change the left margin, or add padding to the left, you need to change the fourth value. (I'm not sure if that's clear?)
For example, if you see something that looks like this:
margin: 5px 0 0 0;
padding:10px 0 0 0;
the left is the last zero, because the order is top margin, right margin, bottom margin, left margin
If it just gives one value, for example:
margin: 5px;
then add the other three values so that you can change the last one. Of course, you can tinker a bit with all the values and see if like the results.
I hope that helps. If any of it is unclear, let me know.
