Steel - Aluminum corrosion (self.bikewrench)

I have a steel frame and I'm looking on getting aluminum parts (eg: seatpost, headset etc)

Is Corrosion a concern?

Will I need to service the bike more frequently?

Is lube between the two metals going to make any difference?

Bare aluminum seatposts love getting stuck in steel frames. I assume headsets will get stuck, too, though I have less experience with those. Using anodized aluminum parts helps a ton. The anodized layer on the surface is mostly inert and prevents further corrosion.
