Blog Help

I am a very basic wordpress user and I am having problems with the following

1. finding a solid blog plugin (top rated). I went to search but it is not easy for me to pick which one is best. I want a simple yet up to date, popular, clean and streamlined blog page for my http://www.parkingangelsapp.com.

2. I tried putting a plugin I found and then I messed up the table of contents so none of them work properly too. It used to be where you would click contact and it would take you down to the bottom of the page, same with about us too. Can you help guide me with fixing this too please?

Thanks everyone for reading and I hope to hear back from someone! =)
