Next year you will do better. It is a process.

It is best to start the seeds in pots, then transplant them when they sprout. This applies to the salad mix as well.

You may find that raised beds work better than tilled earth. After the initial work they are much easier. Weed and pest control efforts are much more focused and therefore more effective. Depending on how you build it, you can sit on the wall of the bed and do the work in greater comfort than kneeling or stooping.

For pictures, just use the Internet, I have found pictures of every plant I ever looked for.

Corn takes about 90 days to mature, ours is just about ready to harvest.

Garlic spray works well against some insects. It does not work against weeds and grass.

Beer traps for slugs are the best. For grasshoppers, we catch them (and other insects) then turn them into "bug juice" and spray the plants once a week. Works wonders.

I will post about out experience at some point.

Good luck!
