Hi Christie,
I’m not a blogger “pro” but I do use blogger for Cat Chat and might be able to help a little.
If you go under “Design” you can make pages which I believe you can display as “tabs” depending on the layout of your blog. (I’m not sure though)
I know you said you don’t like the “gadgets” that Blogger offers but one of my faves for following blogs is their “follow by email” option. Many people prefer to follow blogs that way (I am one of them, right now that is the ONLY way I will follow someone’s blog) since i do not use my blog roll anymore (it became too large).
For Facebook, you can search badges and they give you instructions and a code on how to add them to your blog.
Hope this helped!
