Plant away Jen, most veggie plants don't have roots that are more than 6" deep anyhow and that compost will be decomposed by the time any roots do get that deep.

I would plant but just be aware that the soil will settle over time.
Also I would add some mulch on top of the soil for helping prevent weeds, moisture control and adding to the organic makeup of the soil as it breaksdown
good luck with the maters

Thank you guys.
We had a big storm here last night and when I checked this morning, the soil mix did settle about an inch or so. I am gonna use straw for mulch that hubby has run over a few times with the lawn mower. Looks like I will have to take the hour long trek back into town to get more stuff for the soil mix or pay the higher price to have amazon send it to me.

When you work soil you introduce a lot of air into that mix, along with your compost and other materials. Over time, and rain or a good soaking, helps that air escape and then the soil settles. Over a longer period of time, as the soil bacteria digest the organic matter in the soil, it will settle even more and will loose the ability to hold the air necessary for the Soil Food Web to function.
One thing I have noticed over the years is that you never really get what you think you are getting when buying things sold in cubic foot or cubic yard quantities.
