if you are interested in growing these year after year I would arrange these so you can easily rotate your nightshades (tomatoes, eggplants, peppers)... I would put those in one garden bed.

You need to specify what kind of tomatoes you want and how many... 4 indeterminates would easily fill one 4x8 bed alone if not pruned/suckered.

I would put others in the second bed....
Okra is very tall grow those so they are not shading the others. (although you habe some cooler crops which might like the shade)

We'd need much more information please.

First all of these things are not planted at the same time. Second, some are direct seeded and others grown from transplants. Third, as mentioned there are many different kinds of tomatoes and they come in all kinds of plant sizes.

Fourth, with only 2 4x8 beds your planting space will be very limited so you might consider eliminating a few things from your list unless you plan to only grow 1 each of them.

You might want to check out the Sq. Foot Gardening forum here as a way to maximize your limited growing space as much as possible.
