I'd like to welcome you to Tropical Fish Keeping forum. Glad to have you with us.
As you head into live plants, you may find it helpful to check out the Aquarium Plants section. I have a series at the beginning there about a natural planted aquarium that might interest you.
You will have more success with different tubes for light; what you list is very high in the blue and the actinic is poor for plant growth. This is mentioned in that article, so I won't go into it now.
One caution on the angelfish; this is a shoaling fish that should be kept in a group, 5 or more, which is doable in your 4-foot tank, though other fish will have to be limited, but this will work better when you upgrade to the 75g. I'd wait until then for angelfish, as they should be acquired together to avoid aggression issues that frequently occur when one or two become settled in an aquarium and then regard it as "theirs" exclusively. Danio are not recommended companions for angels due to their high level of activity, angelfish being quiet and sedate. You can read more in our profile; Fish profiles are under the second tab from the left in the blue bar across the top of the page. If the scientific or common name is used in posts exactly as it appears in the profile, the name will be shaded and you can click it to see that profile. Example, Pterophyllum scalare for the common angelfish.
