I can't say much about the tripod other than the reviews I have read rate it quite high. From a photographers point of view though I'd reconsider the head. Get a ball head instead, or something like the
Manfrotto 322RC2, for photography this little beast is awesome. Quick to setup a shot and sturdy when locked. The only exception to this is if you do a lot of panoramas, in which case your chosen head would be better.
You will definitely appreciate the carbon fibre tripod weight difference, if you are used to carrying the p&s. The 7D isn't exactly a light camera, so any weight reduction is a good thing, whilst being sturdy.
