Just know that you will be losing a lot of low end extension if you go with bookshelves over floor standers. For HT, its pretty crucial to have a sub woofer, so if you do go the bookshelf route, I add a sub to the list.
The Polk Monitor 40s and CS2 would be a nice front three if going the bookshelf route. I would suggest the BIC America F-12 sub to accompany them (in keeping the components at the same value level)
