Well perhaps I can help?
My personal choice is Wordpress, it is so robust and easy to use and setup, these days there are many free video's available, that help.
Picking the right theme is up to your own personal choice, there are loads to choose from, for free. The style, the color, the layout depends on the purpose of blog you require. If it is for a business you may want to choose a more formal impression but a personal blog you may choose a bright colored informal selection.
My own blog is BestBlogsSite.com, and I am very proud of it. (you guessed)
My theme I chose was a free theme, I have had many favorable comments on the first impression. If you check out the bottom of the first page you will find the theme name.
Plugins
This is a piece of software someone has written for you, that performs a function within your wordpress blog. Just import it in, adjust settings, and hey presto you have a new blog feature. No programing involved.
I have just posted links for 13 FREE Wordpress Plugins.
There is a catch, however, you will have to visit Best Blogs Site at
http://bestblogssite.com/blog/subscriptions
Dont worry they are FREE, no charge.
Should you not be into Blogging at the moment I am sure you you are in the money making community, and thats what Best Blogs Site is all about. You will find many hundreds of informative articles.
I love helping people
Enjoy
