How do i edit next/previous fonts ?

If you look into your style.css, on line 1070, you’ll see this section:

/* =Navigation
-------------------------------------------------------------- */

.navigation {
	color: #888;
	font-size: 12px;
	line-height: 18px;
	overflow: hidden;
}
.navigation a:link,
.navigation a:visited {
	color: #888;
	text-decoration: none;
}
.navigation a:active,
.navigation a:hover {
	color: #ff4b33;
}
.nav-previous {
	float: left;
	width: 50%;
}
.nav-next {
	float: right;
	text-align: right;
	width: 50%;
}
#nav-above {
	margin: 0 0 18px 0;
}
#nav-above {
	display: none;
}
.paged #nav-above,
.single #nav-above {
	display: block;
}
#nav-below {
	margin: -18px 0 0 0;
}

This is the area you need to edit to change the styles of these links.
