If I'm asked any of these questions I will answer each with a flat "I am neither obligated nor willing to answer this question" (regarding reason for travel, occupation, etc; I don't really care about the name, destination, etc. questions). If they press the issue I'll remind them that we still have the 4th and 5th Amendments, I want an attorney present during questioning but that I cannot afford one (spent my last $5 on the Sept. 11th security fee on my ticket), so they should provide one for me.
