HT Speakers
The receiver is a good start.
I would recommend getting a decent pair of bookshelf speaker for $2-300/pair. Check out some of the ID companies like AV123, Ascend, Axiom, SVS, etc. Locally, look for Polk, Paradigm, Klipsch Reference and others.
If you are set on the HTIB speakers, consider an entry level receiver in the $1-200 price range.
