I am in Richmond, VA, and I can't seem to figure out what is wrong with my American Boxwood shrubs. Stems are covered with little bumps throughout, though no bumps on the leaves. Stems also blackish towards the base. Some leaves show slight discoloration. The shrub seems to be dying from the inside out (meaning from the center of the shrub outwards). Is this a fungus, blight, or hard/soft scale, or something different entirely? Wish I knew. Hoping someone may be able to help identify what condition this is. Thanks
This sounds very much like Boxwood Blight.
Here are some links with more information and some images to help you correctly diagnose the disease effecting your shrubs.

How do I get rid of wooly aphid on my box bushes? I've read this wooly aphid only occurs on ageing apples trees and its not listed on the long list of bugs that eat box. There is no damage as yet to my bushes. But there is wool in every single leaf base with one or two aphids next to the wool.
Wooly Aphids can be found on shrubs, including Boxwood.
Neem Oil is a good treatment for Wooly Aphid and most sucking insects.

An insecticidal soap or neem oil will alleviate your problem.
How to shape and prune a Prunus rotundifolia? I hope I have the correct name here, although that's what it says on the plant label. Also, I would like to know how to shape and prune eucalyptus plants. Both of these plants were planted last September. Thank you in advance for your help.
Rhotundifolia is the bushier and more upright growing form of the Common Laurel or Cherry Laurel.
It can be left untrimmed or be pruned into hedging.
Here is care requirements for both your Laurel and Eucalyptus.

I have a lot of little round shrubs in my yard which I am pretty sure are Boxwoods but not sure what type of Boxwoods they are. I have few that seem to be struggling. I have added photos. They get partial shade/partial sun and are watered 3-4 days a week. Can you tell me how to make them full and lush again.

After light pruning, some brown leaves.
Some browning is normal. If it continues check out the link below to help you figure out why;

Stimulating growth in mature buxus parts that were not exposed to light. I had to replace a very mature buxus topiary for a new one, which, unfortunately, is a bit smaller. This has revealed parts of a neighboring pyramind-shape topiary, which have previously not been exposed to light due to proximity to the old plant. There is no green growth in that area, please see photos). I would be very grateful for any advice on how to stimulate growth in this part of the pyramid to fill the gap between the two plants. Thank you in advance! Anna
Many thanks for the answer LuvaLeigh. Will do so! Fingers crossed it won't take too long :)
The pruning itself will stimulate the cells and allow for new growth. Maintain typical care and add a fertilizer to the mix in early spring. They are not an acid loving plant so use a granular urea fertilizer, 10-6-4.
