italian wines, champagne

[Rbell]

I'm getting married in 5 weeks and I need help with the Italian wine selections and champagne.Does anyone know if the Lamberti Chardonnay, Cabernet Sauvignon, and merlot Santepietre,Delle Venezie wines are good? Also, the N.V. Blanc De Noirs, Domaine Chandon, Napa Valley champagne or the 1997 Brut Domaine Carneros, Taittinger, Napa Valley? Which is the better choice? I appreciate any help. Thanks!
