Picked myself up a bargain-tastic 250GB HDD last night from work for £27 (Maxtor Basics portable one, which I promptly cracked open!) and so what better way to spend a nice, sunday day off work then by fiddling with my atrociously expensive games console? 
That aside, I just want to go through the back-up/restore process before I actually go ahead. I've done a back-up onto a portable HDD before, but it was just a full back-up so it took a while. I believe it'll be quicker this time if I delete the installed game data first, and then just install that as and when I need it?
Also, do downloaded games/demos (from PSN) get backed-up or do I need to download those again? Do I need to do anything in order to ensure I can download them again the next time? I seem to remember something about de-authorising the system first?
Trophies are synced with the server so I have no concerns about those, and I'm aware I need to sync them before I do the HDD swap. What about save games? Better to do copy those to my portable HDD manually?
Can't think of anything else on there that's important, so hopefully I haven't missed anything.
Thanks for any help.
EDIT: Actually, just thought of something. I have two profiles on the console, one is my main one and the other is the one I use for accessing the US PSN Store. Will both of these be backed-up?
