@farmerman,
Yep. I used the companions list to design the layout of my vegetable and herb gardens last year and again this year.
I have my peas, beans, cucumbers, squash and corn near each other. I also have my peppers, tomatoes and strawberries together. In another plot I have my onions, parsnips, carrots and lettuce.
I plant marigolds amongst all the veggies and plant basil amongst the tomatoes. This year I planted rosemary and sage amongst the carrots and parsnips.
I'll post some links to some of my favorite lists that I find to be the most reliable.
This is the most comprehensive one. It has more than the usual and popular herbs and vegetables and also lists the foes as well as the companions. In the case of the herbs and flowers, it tells how the herb or flower aids the companion plants.

This one is from ATTRA, one you'll probably consider to be a reliable source:

At the end it gives a list of sources used to compile the list and properties of the companions/foes.
Here's another ATTRA publication on intercropping and is much more technical:
