The amp is good, but the speakers are AWFUL in comparsion to even budget bookshelf speakers.
Word of advice from a someone thats been there - Buy the amp and the speakers seperately.
Get two pairs of these:
YAMAHA NSBP200PB - £45
WHARFEDALE DIAMOND 9.0 - £39.99
They are one of the better speakers you'll find under £50. They are not great but he quality would be much better than the HTIB speakers you linked. You can find your own center speaker + sub!
