Integration of WordPress into a XHTML eCommerce Website

Brief history… My website was founded in 1995, so I naturally started out by using Blogger. I have a few wordpress non- branded mini sites like offsite community pages, with forums etc. Anyway, I can’t stand blogger anymore and really want to do two things… I did search the forums, and didnt find anything really specific.

1. Make a top level blog page. I’ll show you my website just in case it helps https://www.wigsalon.com. The old setup runs blogger on a subdomain. blog.mywebsite.com – Doesnt look good, once your on the blog its hard to find your way back back home and blogger provides only a fraction of the utility provided by wordpress.

2. I don’t need to make an elaborate theme. My website has two headers, one being everything except the body… The other being just the top portion of my website.

I couldnt find any specific posts or guides to doing this and would appreciate being pointed in the right direction. Also, if you go to my “about us page”, visualize it without the sidebar and a simple wordpress blog… Thats what I want to achieve.

Appreciate any suggestions or guides that might be available!
