Help me update my Wordpress blog

Help Needed to Update WordPress blog I recently moved my [login to view URL] blog ([login to view URL]) over to WordPress. This blog is a part of my business profile and is linked to from my main website, [login to view URL], which is a shopify website built around the Pipeline theme. Using the WP theme 'Twenty-six' I've managed to make the blog look somewhat like my main website, but I want it to look much more similar, in terms of overall look, colour of links, menus and menu style, fonts, header with logo in same position and having same look, etc. I also want a few changes made to the blog post look and sidebar look, for instance: 1. move the date and tags down to the bottom of each post, not in the left sidebar as they currently are on [login to view URL] 2. add a right sidebar section for Social Media links so people can find me on social media, so adding a section that looks just like the current Recent Posts section, but with links to FB, IG, Twitter, Youtube and Reddit. Could also just be symbols added to the blog somewhere, similar to how these links already show up on my main website, see [login to view URL] at the bottom as an example (though at the bottom of the blog pages wouldn't work, they'd need to be in the right sidebar or on the top somewhere). 3. Adding section in right sidebar for opting in to my blog with your email address and incorporating that into my WP. 4. Figure out why the jpgs that are included in the posts are showing up so fuzzy/out of focus and fix that. 5. Starting with June 2012 and going back from there in time, the blog posts are all showing empty spots where images used to be. Would like to figure out what happened to the images and see if there’s a way I can upload them all in again so there aren’t blank spots. If there are, then I may have to look at deleting these posts. And final thing I'd need help with is migrating my old blogger subscribers (who are in a database in Mailchimp) over to WP so that when I do make new blog posts, they go out to my subscribers. See attached pics for some idea of scale of work.
