Hi Mike,

I'm not going to try to answer the question, but rather fill in the types for both cohesion and coupling.

Acceptable Cohesion

Listed in order of desirability.

1. Functional Cohesion
2. Sequential Cohesion
3. Communicational Cohesion
4. Temporal Cohesion

Unacceptable Cohesion

1. Procedural Cohesion
2. Logical Cohesion
3. Coincidental Cohesion

Levels of Coupling

Listed in order of desirability

1. Simple Data Coupling
2. Data Structure Coupling
3. Control Coupling
4. Global Data Coupling
5. Pathological Coupling

These terms are defined in Code Complete, but if you don't have access to it I'm sure you'll be able to find this information on the web.
