They're two points on the same scale, both below what's considered optimal. Insufficient (21–29 ng/mL) is a milder shortfall than deficient (below 20 ng/mL) — both are worth discussing with a doctor, especially if a blood test flags either one.
In theory, yes — Kenya's sun exposure is about as good as it gets. In practice, it depends on how much direct, unfiltered skin exposure you actually get on an average day, which for many people with indoor jobs is very little.

Signs of taking too much can include nausea, vomiting, weakness, and excessive thirst or urination.
