Listing of members' posts in a table?

Hi

I would like to be able to have a few functions for a website which would help a lot.

The site I am doing has members who are writers so they basically have their own “blog). But I want to be able to do some sort of table or block where it lists the member username (or name) and a list of all their blogs / posts. Is this possible via a plugin and if so which one?

Also it would be ideal if a search option was also included so members could search for posts a particular subject. Could be a search on the post tags or the actual content. Any recommendations would be ideal.

Also on our homepage we have latest blogs (a blog on our site is a member) and it appears with the latest person to have joined up. I want to be able to display the latest posts and not the newest member as they may not have written anything at all.

Thanks for any advice.
