Dear Sherry,

First, what a magnificent job you have done so far.  They are really looking good.  The wood will shrink a little bit and lining the beds will help keep the soil and any roots from getting out.  It will also keep weed seeds from collecting in the cracks and growing on the outside of the beds.

If you do line the beds, I would suggest the same weed cloth you used on the bottom.  Letting water escape if needed.  That will also keep the rain from pooling in the beds.  I have left beds unlined and lined others.  I do not see any difference when growing vegetables or flowers in either type with the exception of finding plants like sweet alyssum growing from the cracks in my horizontally positioned wooden sides.

The wood chips are good and bad in the aisleways.  They are a great look and will help to keep the weeds down until they start to break down.  They will be a great addition to your beds or compost pile.  However, the other side of that is they are a great medium with lots of nutrients for weeds.  Any weed seed that drifts into the area and lands in the nutrient thriving wood decomposition will grow like mad.  Weed often and when they are young.  They are easier to get rid of then.  

I have done a garden similar to yours with raised beds and wood chip aisles. This has been my experience. I now remove all soil and chips from the aisleways in order to keep the weeds down. 

I use 20% vinegar with vegetable oil as the only weed (herbicide) spray on my weeds.  This is considered an organic spray. Pour one bottle of 20% vinegar in a one gallon sprayer with about 1/4 cup of any vegetable oil and shake.  The acts as a sticker to hold the vinegar on the weed leaves.  Spray on warm (above 45 degrees), dry, windless days.  It burns the plant.  Shake often when spraying.  This is a chemical and can burn your throat, nose, eyes and skin.  Wear protective gear and do not inhale the fumes if you do decide to use this product.  Hand weeding is easy and very effective when you have baby weeds.

Since you have several beds, you can contact your local soil businesses to find either a garden mix or mushroom compost for your beds.  Mushroom compost works very well. They usually have a minimum of 5 yards.  However, I am not familiar with Tigard's soil businesses.  To determine how much soil you need in yards, multiply the length times the width times the height in feet of the bed and divide by 27.  Measure your depth and leave about 8 inches at the top.  You do not want the soil to spill out when watering.  Garden Supply has a calculator online if you want to use that.

Your refuse collector often sells composted materials as well.  None of the soils are considered organic though when they are in such large amounts.  Local big box businesses and nurseries carry what is termed "organic" raised bed soils but the term is not the same as the USDA organic symbol for food you buy in the store.  The soil companies are not regulated.  However, OMRI labels on the bags of soil tell you that at least the company has used the Organic Materials Research Institute to check a sample of the soil they are selling.  The label indicates that there 'should' be no toxic chemicals in the soil. 

You also need to know that some of the weeds that have strong taproots like dock, mallow and a few others will penetrate the weed cloth.  Grass will entwine all their tiny little roots into the weed cloth making it very difficult to get rid of them if allowed to grow.  And if you used staples to hold the weed cloth in place, anywhere you used them, weeds will grow as they have access to soil.  We live in a verdant, usually very moist climate and most everything grows well here.

Do not cut the weed cloth that you have already placed on the soil.  Your beds are deep enough that most roots will not reach the bottom.

I am adding some links with information on Permaculture and different types of elements to put in your beds.
