You do not have to partition your card.
SOME apps will cue you when you download from the Market asking for an install location.
Some can be moved after the fact. Menu/Settings/Applications/Manage applications/find the app/click move to SD if it's available.
Barcode scanner-it will dl directly to the phone and then it can be moved to the card.
