Wes is still very active on the forum….not sure where you got that info from…Anyways, usually you should hire a designer/developer to make customizations to your site as mentioned here – https://appfinite.com/topic/forum-rules/ But I’ll help out with what I can.
To center your logo, try and add this to your CSS –
.site-header .site-title a {
background-position: center !important;
}
To center your social icons, add this –
.site-header .simple-social-icons {
display: inline-block !important;
}
This is specific to the plugin that you are using, so it probably won’t work exactly for anything else that you use, but the same concept should work if you adjust it for whatever code you add to your site.
Give that a try and let us know if everything checks out.
