Sheldon The straightforward answer is "it depends".
You really shouldn't group all the DB components into a single service class as some must have priority and the TP should remain separate from the DBMS. For example, your IRLM address space must have higher priority than the other DBMS address spaces. Within CICS you will have to decide whether you're going to manage CICS towards a REGION goal or a transaction response time goal and set up you service classes accordingly. Don't make things too complicated, since above a certain limit, your manageability costs will outweigh the benefits.
