Potatoes and Tomatoes are easy, just plant the seeds out of a ripe tomato and cut a potato into a few pieces.
You can likely get these plants locally but they had the Goji berries and hardy kiwi that are hard to get so I will reference their web page.
In the raspberries, I am actually weeding them out in favour of the golden raspberries, they are ever bearing and real good. They came back from the rabbit devastation and with screening have done good last year and the screens do slow down the raccoons but not the squirrels by much so you have to stake the plants up firmly otherwise the weight of the squirrels breaks the branches and you end up with dead plants broken off near the ground.

If you can put down some straw bed for the strawberries you can grow the everbearing (not as big and they seem to not last as long in the fridge (pick and eat)

I plan on mixing this into the strawberry bed this year and around some of the plants I want to put hardwood mulch down around.

If you have room for some of the dwarf apple trees you can get the ones that have 3 or 4 species grafted together and it is amazing how many apples you can get, but you must use the dormant spray in the spring and squirrels can be a big issue and crop reducer.
Disasters for me have been the hardy kiwi, yellow plum, grapes, corn, nectarines and peas the last couple years, the squirrels, raccoons and rabbits are fat though! The blueberries (rest their souls) got ate to the ground by the rabbits and never came back even with screens around them..
