For me, I was able to move the whole 2.3 gb map file to ext sd card by just deleting the TomTom map files located in my internal sd and let TomTom re-download the map to my external SD. As for the TomTom application itself, I went to App manager of HTC and tap on TomTom, it has an option to move to SD. So around 70 mb of the app data gets move to SD. I hope I've answered your questions.
As for your past favorites saved address, the only way I can retain all my favourites is by using Titanium Backup to restore it.
