Just make sure you have a handlebar bag that's easy to unclip and reclip because it will be your purse (actually tell that to your wife) And don't be afraid to wear your spandex in public. Obviously restaurants are different, but we always paraded our bike shorts (and bike short tans).

Also consider getting those panniers that are roll up drybags instead of regular zip ones with pockets. I've used both, and I think I like regular ones better but the drybags are nice because they are huge and you don't need raincovers.
