well i can help answer some of your questions
2. where abouts is ur site is it safe? do u think ppl will come looking around there ?
if not then put up a little fence around ur plants and go to the garden store and get some insect repalent that won't harm your plants (if u have to ask say ur growing tomatoes)
3. depends on where u got these seeds if u bought them then they should be fine but if u've had them for a long time then some might not work and some might be male
