Blogging for Dummies

My blog needs help.  I know I don't post often enough, but the fact that I have one follower, could be why.  I feel that one two are reading this.  Maybe more are looking, but I haven't even had a comment since April.  I know I'm guilty of looking and not commenting, sometimes, too.  I tried a cute template and got it on my blog, then I went to my friend's blog and she just changed hers in the last 24 hrs. to the same template!  So, I finally figured out how to get it off, picked a new one, and it won't let me add it.  Did I disable that somehow?   Also, I have no idea how to shrink my width.  My text in my posts are going all the way to the right side and the text in my title is all the way to the left.   Dana, or those that look but don't let me know, please help! 

Thanks
