ROTH 401k/IRA/Power Point Help?

I have assignment for my computer science class. I need to make a power point about the subject. and the power point has to have 15 slides or more. Requirements:
a) Roth IRA Explanation
b) Roth 401k Explanation
c) Contribution limits for Roth IRAs and Roth 401ks.
d) Differences between Roth IRAs and Roth 401ks.
e) Advantages a Roth 401k might have over a Roth IRA and vice-versa.
f) Can you transfer a Roth IRA to a Roth 401k and vice versa? How? Limitations?
g) Can you have both a Roth IRA and a Roth 401k?
h) Can you contribute to both a Roth IRA and a Roth 401k the same year?
i) 5 good reasons for using a Roth 401k and/or a Roth IRA. Be sure to include the following reasons:
1) tax advantages
2) Social Security's questionable nature
3) Disappearing pensions
4) how much living expenses might be at various points in the future (10, 20, 30, 40 years from now) due to inflation.
I guess my question is can do the project and show what to put on each slide and meet all the requirements.
