I think you mean your fence behind the planter is on the east side of your house, and the planter faces west? If this is 9:30 am, then your fence would be on the east side of your yard :-) I would say your plant choices are great - all liking very full sun. I would plant your Eureka lemon in the far north corner of the planter, as lemons are pretty vigorous citrus cultivars. Kumquats are naturally more compact. I would plant the kumquat next to the lemon, then leave the rest of the planter for your veggies. That way, the citrus trees will not create shade for your veggies. You can plant annuals in there when the veggies are done, until next season.
