It looks good, not sure why canteloupe is in your "tall" section! Are you making multiple beds, or one giant bed? I think building raised beds is a good idea for dealing with your soil. My advice is to have beds that are 3-4 feet wide so you can reach to the middle easily. I would also vote for breaking them up into 10-12 foot long beds, so you don't have to take a hike to get over to the next one.
If you were to ask our fearless leader (Paul Wheaton, this is his forum) he would advocate for really tall hugel beds, like, 6 feet tall, with curvy shapes and random orientations. This will create a multitude of microclimates. Typically one would seed this with a mix and allow the various plants to come up where they like it the best. This would take a lot more woody material than it sounds like you have, however.
As long as you can identify the seedlings (this comes with experience) mixing things up is helpful for avoiding pest disasters. However, if you are new at gardening, planting your seeds in rows will help you identify them from unwanted plants. Think about adding in support species, like an insectary mix from the seed catalog, maybe in patches in every bed.
