Hey, welcome to WebmasterWorld TechieKid.
Almost every CMS app will do this out of the box. Pick one that you like and go for it. Check out CMSMatrix.org
On second thought, in most cases that I know of, you will need to add a plugin/module/whatever to get the tags into the meta keywords, but I wouldn't worry about that. If you have the posts tagged, that's easy to add in the meta tag aspect later.
CMS to check out include CMS Made Simple, drupal, joomla, ModX, etc etc etc. You could also choose to implement this as a forum as well.
I only mention those because they are all LAMP and they've all been mentioned recently. Look through some of the recent threads and you'll see more suggestions. Which one you prefer depends a bit on how much you're techie and how much you're kid ;-)

Can't help you in a LAMP environment... if you were looking at Windows Server hosting I would recommend DotNetNuke. It will do all that you specified - and it's free (opensource). It would take me about 3-5 hours to completely setup a CMS site to do that.
