2 quick simple questions please.

#1: At the very top of my Blog their is this Text title (Dose of Docere).

Can this Text title be replaced with an image?, I have attached the .JPG

#2: The mini-blog on the right hand side on the Home Page features 2 blog posts:

http://www.doceremedspa.com

Can we have the blog work like the Blog on this website below where you can Preview one post and be able to switch to other blog posts?

Please visit that blog here — right hand side where it says "Recent Articles":
http://www.tribecamedspa.com/

Thanks !!
