401K Catch Up Contributions - What to Consider?

[scfr]

I need to decide whether or not I want to start making catch up contributions to my 401K.
Here is the list of questions I have considered:

- Do I need to make catch up contributions in order to meet my retirement savings goal?
- Will making catch up contributions cause shortfalls in my current cash flow?
- What is my estimated marginal tax rate and how much do I expect to save in taxes now if I choose to make catch up contributions?
- Do I like the investment options available in my company's 401K?


Is there anything that I'm missing? Anything else I should consider?

-Will using further tax deferred space reduce one's AGI to a point low enough to contribute to a Roth IRA?
-Will it reduce AGI to a point where you may receive higher education tuition tax credits?
