Is it really important to match the front three speakers to the rears? What are your opinions on this subject?
Welcome to the Forum Skav.
My opinion is that whilst it'd be better to have the surrounds/surround-back speakers matched to the front three than not, it's not 'really important'. Remember that the surrounds/surround-back speakers typically only add effects to a DVD soundtrack.
If your question is also with regard to multi-channel music on the likes of SACD or DVD-A, then I would consider matched rear speakers to be of greater importance. That said, I'd still not consider it critical.
For what it's worth, if you're happy with the speakers you have, I'd just stick with them.
