Considering that some plants prefer more acidic soil than others while other plants prefer a more alkaline based soil that's a good idea. I'd check to see what the ph level of the soil she's using and keep it around 6.0 as every thing in that section of the garden with the tomatoes likes acidic/neutral soil. Though the green beans prefer neutral soil of around 7.0, but can handle 6.0 just fine. Cilantro should be grown in doors. Insects love them and it's close to the lettuce so they'll have additional problem with pests. Carrots though have no reason to be in a raised bed, that's better for the tomatoes and for your back when it comes to harvesting them. If the green house is a typical plastic sheet based one it's better to just grow the herbs in doors. That style of green house offers zero protection from pests.
She'll also want to make sure the soil isn't too rich in clay as many of the plants she's growing don't like it. Also, lettuce should be kept separate because they prefer a more moist soil than other plants. You could drown the other plants.
