Edit URLs for blog posts

[Iwooo]

Hi, how can I edit blog posts URL. 

Now they look like this : domain.com/blogs/entry/XX-name-of-post

and I would like to have it as domain.com/XX-name-of-post . Is it possible to get? Will it colide with other things like posts, comments etc?

If it possible how can I automatically redirect old url to new so I won't get 404 errors. How would 301 redirect look for this? 

Thanks! 

 

P.S Is it possible to get rid of blog categories (the one all blogs have to be in)?
