The derailers should work fine, though I don't particularly like the aggressive looks of the new XTR shadow rear mech, and you can certainly spend a lot less without reducing performance. Check chainreactioncycles.com for NOS (new old stock) Shimano derailers (and hubs, etc.) at great prices. Shipping to the US is very reasonable. (No affiliation, just a happy customer.)
Re. cranks: What's your inseam or PBH? There are a couple of crank arm length calculators on the web. Also take into consideration how high your normal/favorite cadence is. Preference for a higher cadence benefits from a shorter crank for a given leg length. If you want to read something controversial on the topic, try http://www.nettally.com/palmk/crankset.html. But in the end, the difference between 170 and 172.5 is pretty minimal, considering the wide range of lengths cranks USED to be available in. I ride 175s, and have a PBH of 83cm, and keep my cadence just below 80 usually (though I don't really pay attention to cadence...)
