You have to provide some more details, man!
TTL-Camera -> there are thousands out there, which exact model do you use?
SD card -> so you will do that only occasionally? Flash is not a good temporary storage because it wears out (after perhaps 20'000 write cycles or so). But PaulS was asking where you wanna send your data to. An internet server? Some public service?
GPRS -> there are at least a dozen GPRS shields available in shops. Which exact model do you use?
If you cannot provide links to the details of your resources, make some photos of the components and post them. If you wanna keep this information secret: help yourself.
