Blogger template tune up

Hello everyone. We have a blog template - [login to view URL] we want to tune up and have ready and working Over this template we'd like to: >Add our logo where it says QUICKLY. Add link to our page >Teach me how to change the background texture in the header ( the grey circles in the top part of the design) >Change tipography. We use VAG ROUNDED and ARIAL >Make this sections in the blog: HOME where all our posts go together And then sections that show posts according to the tags Yoga Pilates Nutrición Vida Sana >FEEDS/WIDGETS: We need Twitter and Facebook >Contact Page with a text, our email with a mailto link and a contact form with a send button (probably jotform, something like this one [login to view URL] ) >We want to allow comments , can a captcha be added? We have ZERO idea of blogger so we need the blog to be fully working, and we need to know how to add new posts etc. A think that is all, thanks and good luck
