Shimano 105 5700 groupset?

I currently have a Specialized Allez Sport with upgraded Mavic Aksium wheels.
for a while I have been thinking about replacing the whole groupset for the Shimano 105 5700.
I have two questions regarding this, I am not sure if the bottom bracket included with the 105 groupset will fit in my bike. the current bottom bracket is a Shimano, outboard cartridge bearing, 68mm. I am guessing that 68mm refers to the case width? the case width on the bottom bracket that comes with the 105 group set (Shimano 105 SM-BB5700) has a 68mm to 70mm case width.
the second question is how much will it cost to have the whole groupset changed, and the cables too of course? I have found the whole group set for about £400, but I haven't been able to find any prices for fitting.
any ideas guys?

A mate has just done similar, purchased the groupset from Merlin for £340 with the 10% off at the mo, a local lbs quoted £40 for putting the groupset on but I've read of some folk getting charged up to £80, if you strip the old stuff off it may work out cheaper too. The BB is fine.0

Thanks for the help mate.0

The question still remains. if I upgrade my Allez Sport with the same 105 5700 group set as the Tarmac Elite, even though the Tarmac has the FSA Gossamer Pro crank set and a different bottom bracket, and the 105 group set has a 10 speed 105 cassette and the 105 chain instead of the Tiagra cassette and chain fitted to the tarmac, which will be the better bike? a stiff alloy frame with alloy bars, an alloy seat post and carbon front forks, or an all carbon frame with a carbon seat post and alloy bars?0

Whichever one suits you best will be the best.0
