A Few Little Questions / Concerns / Queries...

From the photo, the breeder has given you a show lead. You need a proper collar and lead for walking.

I don't bother getting them used to having a lead on, just pop it on and carry them outside to go for a little walk, usually i will drive to the local park and take an older dog with me so they have another to follow and see what is interesting.

Stand is quite a difficult one to teach if you have already done 'sit' (this is why a lot of show people don't teach a sit), I get the pup used to being stacked and rewarded for standing and sit happens just by waiting for pup to calm down for food to be put down, later I can add the word to the action.

down can be taught from a stand, taking the treat low and then slowly between the front legs. or you can get the dog to follow the treat under a low obstacle so she has to crawl, as sson as she drops you can reward.
