I don't know your USDA zone, but tomatoes and bell-peppers are usually my main crop (Paste tomatoes, slicing tomatoes, and cherry tomatoes).
The soil should be relatively loose, though tomato roots don't extend far, and they need to be watered semi-regularly (about every three days - I have mine on irrigation with a timer, but prior years I watered with a hose just fine). You should start them indoors ASAP under a light or infront of a south-facing window, and then plant them outdoors after the last frost. I started mine two weeks ago, but the growing season in Missouri is short - your growing season may be larger than mine. Even if not, you'd still do fine if you get the seeds started indoors within the next ten days.
If you get a good enough crop, you can pressure-can homemade salsa, pasta sauce, and tomato chutney (if that's something you use! We go through probably two gallons of tomato chutney a year - 1 quart per French Meat Pie; eight pies a year).
Also, depending on how much ground space you have, I get good results with cucumbers and Waltham Butternut Squash (this is similar breed to what's used for store-bought canned ""Pumpkin"" puree, and we use it for pumpkin pie. You can also grow pie pumpkins, and mix the two, but really, Waltham Butternut Squashes are superior in a half-dozen ways (easier to grow, more productive per vine, easier to scrape out the flesh after oven-roasting, consistent taste (some pumpkins taste terrible - they vary too much), etc...).
I haven't had any luck with corn, but others seem to do that fine, so I always plant it anyway (and never harvest any!). You might have better luck than me, and it never hurts to plant them. Cucumbers, squashes, melons, corn all get planted outdoors (no need to start indoors), usually around May 1st (in my area).
