I'm going to answer a slightly different question: "For those three aspects of life (family, church, small business) are there studies that do show that blacks value those more or less than other races?"
I wasn't able to find any studies that on appreciation of small business success for African Americans. They do own less small businesses.
Lack of focus on family
I'm not sure how to measure exactly that so I'll just cite statistics that can be seen as proxies.
Finding a suitable spouse is hard. Finding a spouse where there is about a 33% chance of him being incarnated or higher poverty rates certainly doesn't make it easier - as seen in "Understanding Young Women's Marriage Decisions: The Role of Labor and Marriage Market Conditions" (Francine D. Blau, Lawrence M. Kahn, and Jane Waldfogel).
But if those two are controlled for there are virtually no discrepancies in marriage rates between whites and blacks.
What about divorce rates? Blacks divorce consistently (page 26f) (e.g. for all unemployment and age of marriage levels) more often.
A further measure is percentage of out-of-wedlock births. About two-thirds of African American children are born out of wedlock (the study does not attempt to control those figures with income levels. It does find that income correlates well (0.6) with out-of-wedlock births).
This is further exacerbated by the fact that black married woman get less children than black white woman. From the pictures I'm eyeballing a difference of 20%. That would mean the the two-thirds would need to be reduced by a fifth (so 0.53).
That does not mean an absent father figure nor lack of male role models (see "The Black Extended Family" (E.g. the US census 2003 showed that black kids are three times more likely than whites to live with their grandparents) and "Joyce Ladner, Tomorrow's Tomorrow: The Black Woman 2") or even that values historically seen to be taught by the father can not be taught by mothers.
Lack of focus on church attendance
A Gallup poll from 2010 showed Hispanic black attendance on 52%, non-Hispanic black attendance on 55%.
That puts them on par with the stereotypical religious segments (People from the south, Republicans, conservatives, People older than 65) who range from 51 to 55%.
AFAIK there are not studies on how much income affects church attendance for blacks. For non-Hispanic whites there is a direct positive correlation between education (which has an correlation and plausible causation to income) and church attendance.
