I would go with cross-3 on the 32 spoke front wheel and not cross-2. With cross-2 using DT Competition spokes, the crossing point will still be on the thick part of the spokes which will give them quite a bend. But I use a wheel like that and I never had a problem with it.

I personally would go with Dura-Ace hubs over DT 240s even though they weigh a little more.
