As far as I know, also being new to MVC - if you want the convenience of 3rd party controls, drop mvc and use webforms. If you want to cut back on markup and 'tag soup' as I've heard it called, check out using a custom viewengine. The release candidate of MVC3 is out and I believe it has the Razor view engine, which is a mix of c# and xhtml.
See: http://weblogs.asp.net/scottgu/archive/2010/07/02/introducing-razor.aspx
Hope that helps!
EDIT
In response to some comments about my post - I recommended he drop mvc and switch to webforms because of the amount of user controls for webforms. I was under the impression that I could ignore everything in the 'toolbox' tab in visual studio once i switched to using MVC because it didn't use controls the same way.
If you were just looking for easy ways of adding some 'zazz' to your site, why not use a javascript library like jQuery, I use it extensively on my MVC site and there are tons of plugins for it such as wysiwyg html editors, image crop tools and anything else you need. Sorry if saying 'drop mvc' caught you off guard. I love MVC.
