i would use those cranks if you're on a budget, but they will add a nice vintage look to your bike. if you're going to get new cranks, finding a cheap bb won't be a problem. there are many out there and are very affordable. you can probably sell the crankarms on ebay.
the mavic cxp22 will probably be the most recommended for their durability. they will be cheaper than any deep v. if you're looking for something cheaper, bens cycles has an alex wheelset with flip flop hub for under 100.
and as for the wheels (27 to 700c), there shouldn't be any problem.
