I would agree, as I remember The Christmas Invasion Special, when Rose says that the Doctor is part of the TARDIS translation circuit and when he was lying in bed from the regeneration, the translator didnt work!
When the Doctor woke up then everyong on the Sycorax ship can understand each other humans and Sycorax!
So I think we can say that yes the Doctor speaks Gallifreyan all the time, but he and the TARDIS translate spoken languages.
.
I wonder though if the written languages are just done by the TARDIS as a slightly separate thing?
Anyway the point about the Doctor's age is that, if he always speaks Gallifreyan (and we have kind of proven he does!), then he must be counting in Gallifreyan years and thats translated to the year used by whoever he is speaking to!
So if this is the case then we will always get it as Earth years due to the translation!
