10 crowns is a usual retail unit. Sometimes you can find individual crowns at a retail store, but that's just a matter of pricing. Ten plants is a good place to start.
I don't know about a 4x8 frame - that might be kind of on the small side. The asparagus plants are pretty hardy - usually it is planted in a wide trench. The crowns are the roots of a plant - many roots coming together into a central crown - like an octopus. The plant is set in the trench by spreading the leg roots out, with the central crown in the middle of the trench, then cover with a layer of dirt and compost. You will only cover the roots, not bury them. As each season goes by you add more dirt and compost to the trench, eventually burying them and leveling the trench. The soil protects the plant from freezing (you may have to consider the depth of the winter freeze in your soil, I don't know). After 2 or three years you will see the thin spears being replaced by thick, substantial spears.
We have a book called "Encyclopedia of Organic Gardening" by Rodale. It is an old book - written in 1959. The book has been reissued, but is a shadow of it's former self. The old copy we have is 1145 pages, the newer not even half that size. You can find this old book used on the internet. They recommend a trench 10 inches wide by 12 inches deep. Place a 3 inch deep layer of mature compost humus (good compost mixed with dirt). This layer should be wel dug into the bottom of the trench. The crowns should be placed 18 inches apart, rows not closer than 4 feet. Here we hit some confusion - I took the 18 inches to mean crown to crown (center to center, as with joists). The 4 feet between trenches I took to mean 4 feet of undisturbed dirt between one edge of the first trench and the adjoining edge of the next trench.
We have bad soil here - it is called "chert". Looking at an exposed/eroded bank, you would assume it is clay because of the red color. But it is hard/flinty rock surrounded by dirt. When we dug our two trenches, they were the width of the roto-tiller. It was tough going. We repeatedly ran the tiller through the trench, each pass getting a little deeper, and piled the dirt removed on the sides of the trenches. The soil was so rocky that we ran it through a sieve (sp?) - much faster than trying to pick all the rock out. The sieve was nothing fancy - we took the door off the chicken house and ran it through the hardware cloth on the door. Anyway, the result of all this was a pile of rock waist high and well broken up soil for refilling the trench. We didn't have a crop of compost yet, so we used bags of composted manure purchased at a local feed store. If you dig the sod off before tilling, the sod can be placed green side down in the bottom of the trench to provide organic matter before putting the dirt in the bottom og the trench.
It was a lot of trouble to go to, but asparagus is a little different from most crops - it is a perennial, so do it right once and never deal with it again. After that, it's a matter of adding organic material and additional fill dirt to the top of the trench every year. The neighbor has a bed that is 7 years old - looks like a jungle in August with all the ferns leafing out. The plants fill in thicker and produce more with every passing year, reseeding themselves as noted in a previous post. I like to look at the patches the farmers have when we're buying produce during the summer - most of them are growing it for personal/family consumption.
I should think the different grades of crown being sold are a matter of age - could be mistaken. Maybe they are plats that bear more than their siblings. I guess the setermining factor of which plant you buy is a matter of how much your money is worth compared to the time you'll wait . We used year olds - the typical crown for sale, and in 3 years you'll be munching on it while working in the garden.
