I used the factor variable notation that is new to Stata 11, 
so I let Stata make those dummy variables for me. You can do 
it either way, create dummies yourself and add those or use 
Stata's factor variable notation.

That is a question that can only be answered by you. I do 
not know all the details of your data, your project, your 
theory, your subsequent analysis, your intended audience,
etc., etc.

It is good practice to ask such questions on the statalist,
as is discussed here:
