How to seperate individual blogs?

Hey

Having problems seperating blog posts.
For example if you click on a blog post it takes you back
to the top of the blog page, so you therefore cannot e-mail
someone an individual blog post, they have to just go to the blog
page and then scroll down to a blog they want to read.
I have played around with permalinks but that hasn’t sorted out the
problem, can anyone suggest a solution?

Also the older entries button at the bottom of the page takes you to
the homepage rather than to older entries, can anyone suggest what to
do about this? Can’t seem to find anywhere to edit this option?

The web page i am talking about is:

Many thanks
