So Confused!

I've been trying to set different things up on this blog and I'm so confused. I've been at it for days now. I'm very new at this and I'm having a hard time. Calgon take me away!!!
I'll keep trying but bare with me here, remember the first time you set up your blog an it wasn't so simple either! I'm doing this on my own without any help. Is there any quick tips you don't mind sharing.. I'm around!
Thanks!
