Perhaps - but I didn't get any sense of "We'll use these 13 TARDISes in this eleaborate plan I've been plotting for 1200 years to .. err... I don't know what!" I definitely got the sense he knew exactly what he was doing. Maybe I need to watch it again!
Like you need an excuse to watch it again?
The issue isn't that the Doctor didn't know what he was doing. He knew, but if he remembered, he'd not be what he now is.
When we first see Eccelston, he think's he's effectively destroyed both the Time Lords and the Daleks. My memory (which could be wrong) is that the implication was that he'd put in the Time Lock, so that, aside from himself, they pretty much never existed. Most folk didn't remember what a Time Lord was - not just due to passage of time for mere mortals, but because he'd pretty much (but not quite totally) erased them from history.
The Daleks we see first are ones that, one way or another, avoided the Time Lock.
Now, to not disrupt history, and to ensure he stays the hoopy frood we all love, the Doctor cannot remember what he did. And the Time Lock on all these events must also still be in place to explain the non-existence and re-appearance of Daleks. So, while the Doctor went and hid Gallifrey, he doesn't know where he put it, and any evidence that it was done is in the Time Lock!
That's where the Curator* and
Gallifrey Falls No More come in. It is one bit of Gallifrey in the final hours that sits *outside* the Time Lock, where the Doctor can eventually see it, and the Curator can plant the idea in his head that the rest of Gallifrey is also *outside* the Time Lock, but in stasis and tucked away somewhere.
*Upon thinking - the Curator is probably like the Valeyard or the Watcher - he's the final distillation of the Doctor, retired, that can wear the Doctor's past faces, though aged. Thus, they can have the past actors (or lookalikes) play the role of the Curator from time to time....
