Matt, I have one more suggestion...
If you keep your beds 4'x4' or 5'x5', you can reach all the way to the center while sitting on the edge of your bed. That makes it super comfortable to weed, plant, and whatever. You might want to do a little "mock-up" to see how far you can reach and what is comfortable. You could also make them 4'x8' or even longer, and achieve the same results.
An 8'x8' bed sucks ass because you plant them tight, then you can't get in there to harvest or weed, and you also end up walking in there, which is the very last thing you ever want to do. It compacts the soil and defeats all the work you just did.
Trust me, you'll be thrilled with them if you keep them skinny. Like I said, 4' or 5' wide. I kept all mine 4x4, 4x8 and 2x8 for flowers and bulbs. At one time I think we had like 26 of them and I had them all tubed up for irrigation. It was wicked cool.
(That was on top of five acres of orchards, two other 50'x100' gardens, and a 10x10 purple sunflower garden, among tons of other stuff. )
