A T-cross in a chart indicates a focusing of energy on the planets/place where the squares occur: So in your chart there is a focus on Taurus (physical) Sun (self-expression) conjunct (energy is combined with) Moon (home, also emotions) focused in the 4th house (home, also emotions). This could indicate strong emotional self-expression.
"Emotional self-expression" is just what it sounds like: the person with this energy will tend to express themselves emotionally. Perhaps the person will be very passionate about the things they believe in or will express themselves very strongly and emotionally about issues they are interested in.
In interpreting, it helps to use the "astro-sentence" of SIGN modifies PLANET focused on HOUSE. Knowing all three (Sign, Planet, and House) gives the best interpretation of a person's chart. For more about the "astro-sentence" see: http://www.geocities.com/wilsontctc/
