I don't own a GSD myself ( parents' GSD, not mine), so I can't answer much of your question. I'm a dog owner myself ( love local mutt), and I suppose I could share some very basic info.
Vaccine: for starter, your pup needs 3 to 4 shots, price varies with type of vaccine you choose ( ranging from RM35 - RM65 each shot), followed by annual booster.
Heartworm prevention: can choose between that ONCE A YEAR proheart injection, or ONCE A MONTH heartgard chewables consumptions. Price goes by weight, the heavier your dog is the more it cost.
Dewormer: can get those cheapo RM1/ pill type or can get quality type at RM5 to RM10/pill depending on what brand and where you buy.
Food: it is really up to dog owner to decide, but I recommend getting those better quality food rather than some overpriced crap that is famous due to their marketing technique.
Personally I use to feed Arden Grange, Acana/ Orijen...etc but now switched completely to prey model diet. So it is really up to you to decide though.
Just a thought: Spend more on better quality dog food now rather than spending huge amount of money and heartache for vet bills later on.
Accessories, You will need:
Collar for your dog
Harness ( optional)
Leash
Poop bag ( can use normal plastic bag or buy a poop bag)
Toys
Water/ Food bowl
Others:
Training Treats ( can buy commercial treats or make it yourself)
Hygiene Care ( ie shampoo, disinfectant to clean dog place...etc)
Classes ( puppy classes/ basic obedience training)
Supplement ( if you give good food, shouldn't need it, but as dog age, esp big dog, might need certain supplement for the hip & joints...etc, others are optional ie salmon oil/ fish oil la, brewer yeast la...etc)
Time:
Walks/ exercise, these do not refer to short 2 to 5 minutes walk from your house to place nearby for your dog to poop. Real exercise as in letting the dog run/ play/ physical actions.
Bonding: takes time, no amount of money can do this
Research: constantly updating your knowledge, not only through internet but also discussions and sharing sessions. Research and updates on dog food ( this can be controversial, or sometimes even scandalous, so never trust commercial pet food 100% without updating news from time to time), reading up about dog care/ dog breed special needs..etc there are a lot of info out there, but it takes time to filter out those real genuine scientific proven research from other piles of craps, knowing why and what to look for in your dog food ingredient, if you feeding raw, more to read on why feeding this and not that...blah blah, a lot of readings.
Stop here, continue when home.
Key of owning a dog is to know the very basic needs of keeping a dog, then only into breed specification. Yes, different breed has different needs, but at end of the day, they're still dog, so get through the general knowledge about dogs ( any dogs, any breeds), then only do specify readings on breed, that will enable you to understand GSD better.
